Ingredients

• 1 pound flat iron steak
• 3 tablespoons olive oil
• 3 tablespoons lime juice
• 3 garlic cloves, minced
• 2 teaspoons chili powder
• 1 teaspoon paprika
• 1 teaspoon ground cumin
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 red bell pepper, sliced
• 1 green bell pepper, sliced
• 1 yellow onion, sliced
• 8 flour tortillas
• 2 tablespoons fresh cilantro, chopped
• 0.5 cup sour cream (optional)
• 0.5 cup guacamole (optional)

Directions

Step 1

In a small bowl, prepare the marinade by combining olive oil, lime juice, minced garlic, chili powder, paprika, cumin, salt, and black pepper.

Step 2

Place the flat iron steak in a sealable plastic bag or shallow dish and pour the marinade over the steak. Ensure it is evenly coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes or up to 4 hours.

Step 3

Preheat a skillet or grill pan over medium-high heat.

Step 4

Remove the steak from the marinade and let any excess drip off. Cook the steak for 4-5 minutes per side for medium rare, or until your desired doneness is reached.

Step 5

Transfer the steak to a cutting board and let it rest for 5 minutes before slicing it thinly against the grain.

Step 6

In the same skillet, add the sliced bell peppers and onion. Cook for 4-5 minutes, stirring often, until softened and slightly charred.

Step 7

Warm the flour tortillas in a dry skillet or microwave just before serving.

Step 8

Assemble the fajitas by adding slices of steak, cooked peppers and onions to each tortilla. Top with cilantro and, if desired, sour cream and guacamole.

Step 9

Serve immediately and enjoy!
