Instructions
Step 1: Marinate the Steak
- In a bowl, whisk together olive oil, lime juice, chili powder, cumin, garlic powder, paprika, salt, black pepper, and red pepper flakes.
- Add the sliced steak and toss to coat. Let marinate for at least 10 minutes (or up to 1 hour for deeper flavor).

- Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
- Add sliced bell peppers and onion, season with salt and black pepper, and sauté for 5-7 minutes, until tender.
- Add garlic and cook for 30 seconds. Remove veggies from the skillet and set aside.
Step 3: Cook the Steak
- In the same skillet, add the marinated steak and cook over medium-high heat for 2-3 minutes per side, until browned and cooked through.
- Remove from heat and let rest for 5 minutes, then slice thinly.
Step 4: Assemble & Serve
- Warm the tortillas (or prepare lettuce wraps).
- Fill each tortilla with steak, fajita veggies, and desired toppings.
- Serve with lime wedges and fresh cilantro.
