Ingredients List

For the Steak Marinade:
1 lb flank steak or skirt steak
1/4 cup olive oil
2 tablespoons lime juice
3 cloves garlic, minced
1 tablespoon chili powder
1 teaspoon cumin
1 teaspoon smoked paprika
1/2 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon onion powder
1/2 teaspoon garlic powder

For the Fajitas:
1 red bell pepper, sliced
1 yellow bell pepper, sliced
1 green bell pepper, sliced
1 onion, sliced
1 tablespoon olive oil
Tortillas (corn or flour, for serving)
Fresh cilantro, chopped (for garnish)
Lime wedges (for serving)

Instructions

1. Prepare the Steak Marinade
   In a small bowl, whisk together olive oil, lime juice, garlic, chili powder, cumin, smoked paprika, salt, pepper, onion powder, and garlic powder. Pour the marinade over the steak and let it marinate for 15 minutes to 1 hour.
2. Grill the Steak
   Preheat your grill or grill pan to medium-high heat. Grill the steak for 4–5 minutes per side, or until it reaches your desired level of doneness. (For medium-rare, aim for an internal temperature of 130°F–135°F.)
3. Sauté the Vegetables
   While the steak is grilling, heat 1 tablespoon olive oil in a large skillet over medium heat. Add the sliced bell peppers and onion. Sauté for 5–7 minutes, stirring occasionally, until the vegetables are softened and lightly charred.
4. Rest and Slice the Steak
   Once the steak is done grilling, remove it from the heat and let it rest for 5–10 minutes. After resting, slice the steak thinly against the grain.
5. Assemble the Fajitas
   Warm the tortillas on the grill or in a dry skillet. Place a few slices of steak on each tortilla, top with sautéed bell peppers and onions, and garnish with fresh cilantro and a squeeze of lime juice.
6. Serve
   Serve immediately with extra lime wedges and your favorite salsa or guacamole.

Additional Notes

• For extra flavor, marinate the steak overnight.
