Ingredients
Scale
1.5 lbs flank steak or skirt steak, sliced against the grain into thin strips
1 large yellow onion, sliced
2 bell peppers (one red, one green), sliced
2 tablespoons olive oil, divided
1 teaspoon salt
1/2 teaspoon black pepper
12 small flour tortillas
For the Marinade:
1/4 cup fresh lime juice
1/4 cup olive oil
2 cloves garlic, minced
1 tablespoon chili powder
1 teaspoon ground cumin
1/2 teaspoon dried oregano
1/4 teaspoon cayenne pepper (optional)
Instructions
Combine all marinade ingredients in a bowl. Add the sliced steak, toss to coat completely, and let it marinate for at least 15 minutes while you prepare the vegetables. For best flavor, marinate for up to 4 hours in the refrigerator.
Heat 1 tablespoon of olive oil in a large, heavy-bottomed skillet or cast-iron pan over medium-high heat until shimmering.
Remove the steak from the marinade, letting excess drip off. Add half the steak to the hot skillet in a single layer. Sear for 2 to 3 minutes per side until browned. Do not overcrowd the pan; cook in batches if necessary. Remove the cooked steak and set it aside.
Add the remaining 1 tablespoon of olive oil to the skillet. Add the sliced onions and bell peppers. Cook, stirring occasionally, for 5 to 7 minutes until the vegetables are tender-crisp. Season with salt and pepper.
Return all the cooked steak to the skillet with the vegetables. Toss everything together for 1 minute to reheat the steak and combine the flavors.
Warm your tortillas according to package directions (in a dry skillet or microwave).
Serve the sizzling steak and vegetable mixture immediately with warm tortillas and your favorite toppings.
Notes
For the best restaurant-style sear, use a cast-iron skillet and let it get very hot before adding the steak.
If you prefer a sheet pan method, toss the marinated steak and vegetables with 2 tablespoons of olive oil and roast at 400°F (200°C) for 15 to 20 minutes.
This recipe uses flank steak, which is excellent for absorbing the marinade and cooking quickly.
