This is a wonderful recipe for busy weeknights when you want something homemade, flavorful, and easy to prepare.

Ingredients:

For the Fresh Tomato Salsa
3/4 c. tomatoes, chopped
1 onion, chopped
1 jalapeno pepper
1 Tbs. lime juice

For the Beef and Vegetables
1 lb. beef roast
3 cloves garlic, minced
1 tsp. cumin
1 1/2 tsp. chile pepper
1 Tbs. olive oil
1 bell pepper, sliced thin
1 onion, cut into thinly sliced half rings
1 jalapeno pepper, sliced
salt and pepper to taste
8 small tortillas, warmed if desired

Directions:

In a small bowl, combine the chopped tomatoes, chopped onion, finely chopped jalapeño, and lime juice. Season with salt and black pepper to taste. Cover and refrigerate while you prepare the beef and vegetables.

Trim any excess fat, silver skin, and tough connective tissue from the beef roast. Slice the beef thinly against the grain, about 1/4 inch thick. Cut the strips into shorter pieces if desired.

In a small bowl, combine the minced garlic, ground cumin, and chili powder. Sprinkle the seasoning mixture over the beef strips and toss until evenly coated.

Heat the olive oil in a large cast-iron skillet over medium-high heat. Add the sliced bell pepper, onion, and jalapeño. Stir-fry for 5 to 8 minutes, or until the vegetables are crisp-tender. Transfer the vegetables to a bowl and keep warm.

Add half of the seasoned beef to the hot skillet, spreading it into a single layer as much as possible. Stir-fry for about 1 to 2 minutes, or until browned and nearly cooked through. Transfer the beef to the bowl with the vegetables.

Add the remaining beef to the skillet and stir-fry for another 1 to 2 minutes, or until browned and cooked through. Thin strips cook quickly, so watch them carefully to avoid overcooking.

Return the cooked beef and vegetables to the skillet. Toss together and cook briefly until everything is heated through. Season with additional salt and black pepper as needed.

Warm the tortillas in a dry skillet or according to the package directions.

Spoon the beef and vegetable mixture into the warm tortillas. Top with the chilled fresh tomato salsa and serve immediately.

Enjoy!

Tips for Best Success:

• Slice the beef against the grain. This shortens the muscle fibers and helps make each bite more tender.
• Cut the beef into thin, even strips. Thin slices cook quickly, making this a great recipe for busy evenings.
• Don't overcrowd the skillet. Cooking the beef in two batches helps it brown instead of steam.
• Keep the vegetables crisp-tender. You want them softened slightly but still retaining some texture and color.
• Adjust the heat to your liking. Remove the jalapeño seeds and membranes for a milder flavor, or leave some in for extra heat.
• Prepare the salsa ahead. Making it while the beef cooks saves time. You can also prepare it earlier and refrigerate it until supper.
• Avoid overcooking the beef. Thin strips can become tough if cooked too long. Use the suggested cooking times as a guide, and make sure the beef reaches a safe internal temperature. For whole-muscle beef, the USDA recommends 145°F followed by a three-minute rest; thin strips may need a different cooking approach to verify temperature accurately.

Variations and Substitutions:

• Use a different cut of beef. Sirloin, flank steak, or skirt steak can work well. Slice any cut thinly against the grain.
• Make it milder. Omit the jalapeños or replace them with a little extra bell pepper.
• Add more vegetables. Mushrooms, zucchini, or thinly sliced red bell pepper would be delicious additions.
• Try a different seasoning blend. A favorite taco seasoning can replace the cumin and chili powder. Start with a modest amount and adjust to taste.
• Change the tortillas. Use flour or corn tortillas, depending on your preference.
• Make it a rice bowl. Skip the tortillas and serve the beef and vegetables over rice.
• Add a creamy topping. A spoonful of sour cream, plain Greek yogurt, or sliced avocado makes a tasty contrast to the spicy beef.
• Make the salsa your own. Add chopped cilantro or a little extra lime juice for a fresher, brighter flavor.

Serving Suggestions:

These beef and vegetable tacos make a satisfying meal on their own, but they're also delicious with a few simple sides.

• Mexican-style rice
• Refried or black beans
• Corn on the cob
• Chips and salsa
• Fresh avocado or guacamole
• A simple green salad

For a quick weeknight dinner, warm the tortillas, set out the toppings, and let everyone assemble their own tacos.

How to Store:

 

• Refrigerating leftovers: Allow the beef and vegetables to cool, then transfer them to an airtight container. Refrigerate within two hours of cooking and use within 3–4 days.
• Storing the salsa: Keep the fresh tomato salsa in a separate airtight container in the refrigerator. For the best texture and freshness, use it within 2–3 days.
• Freezing: The cooked beef and vegetables can be frozen in a freezer-safe container for up to 2–3 months for best quality. Thaw overnight in the refrigerator and reheat thoroughly. The fresh tomato salsa is best made fresh because freezing can change the texture of the tomatoes and onions.
• Reheating: Warm the beef and vegetables in a skillet over medium heat with a small splash of water if needed. Stir occasionally until heated to 165°F. Avoid reheating longer than necessary, as the beef can become tough.
• Warm fresh tortillas just before serving for the best results.

Frequently Asked Questions:

What is the best cut of beef for stir-fry tacos?

Sirloin, flank steak, and skirt steak are all good options. You can also use a beef roast, as this recipe calls for. The important thing is to slice the meat thinly against the grain so it is easier to chew.

How do I keep the beef tender?

Slice it against the grain, cook it in small batches, and avoid overcooking it. A hot skillet helps the beef cook quickly without sitting in its juices for too long.

Can I make this recipe less spicy?

Yes! Omit the jalapeños or remove their seeds and membranes before slicing. You can also reduce the chili powder to suit your family's taste.

Can I prepare anything ahead of time?

Absolutely. Chop the vegetables, prepare the salsa, and mix the seasonings ahead of time. Store the salsa and prepared ingredients separately in the refrigerator until you're ready to cook.

Can I use frozen vegetables?

Fresh vegetables provide the best crisp-tender texture, but frozen bell peppers and onions can work in a pinch. Thaw and drain them well, and expect a softer texture and a little more moisture in the skillet.

Can I serve this without tortillas?

Yes! Serve the beef and vegetables over rice, in a salad bowl, or alongside beans and your favorite vegetables. The fresh tomato salsa works well as a topping for all of these options.

Is this recipe good for meal prep?

Yes. Cook the beef and vegetables ahead and portion them into airtight containers. Store the salsa separately and add it after reheating. Keep the tortillas separate so they don't become soggy.

How can I tell when the beef is done?

The thin strips should be browned and cooked through. For food safety, whole-muscle beef should reach 145°F with a three-minute rest. Because thin strips are difficult to check individually with a thermometer, use a suitable thermometer and avoid relying on color alone.
