Ingredients

• 1 pound beef flank steak
• 1 large red bell pepper
• 1 large green bell pepper
• 1 large yellow bell pepper
• 1 large onion
• 2 tablespoons olive oil
• 2 whole lime
• 1 teaspoon ground cumin
• 1 teaspoon paprika
• 1 teaspoon garlic powder
• 1 teaspoon chili powder
• 0.5 teaspoon black pepper
• 1 teaspoon salt
• 8 small soft corn tortillas
• 0.5 cup sour cream
• 1 large avocado
• 0.5 cup fresh cilantro leaves
• 0.5 cup grated cheddar cheese

Directions

Step 1

Begin by slicing the beef flank steak into thin strips against the grain to ensure tenderness.

Step 2

In a mixing bowl, combine olive oil, juice of one lime, ground cumin, paprika, garlic powder, chili powder, black pepper, and salt. Mix well to create the marinade.

Step 3

Add the beef strips to the marinade, ensuring each piece is well-coated. Set aside to marinate for at least 15 minutes.

Step 4

Slice the red, green, and yellow bell peppers into thin strips. Then, slice the onion into thin rings.

Step 5

Heat a large skillet or cast iron pan over medium-high heat. Add a tablespoon of olive oil.

Step 6

Add the onion and bell pepper strips to the skillet, sautéing for about 5 minutes or until they are softened and slightly charred. Remove the vegetables from the skillet and set aside.

Step 7

In the same skillet, increase the heat to high and add the marinated beef strips. Cook for 5-7 minutes or until the beef is cooked through and has a nice caramelized color. Ensure not to overcrowd the pan to allow for proper searing.

Step 8

Return the cooked peppers and onions to the skillet with the beef, squeezing the juice of the second lime over the top. Mix everything well and cook for an additional 2 minutes to let the flavors meld.

Step 9

Warm the corn tortillas in a clean skillet or directly over a gas flame for about 30 seconds per side until pliable.

Step 10

Assemble the tacos by placing a generous amount of the beef and vegetable mixture onto each tortilla.

Step 11

Top with a dollop of sour cream, slices of avocado, a sprinkle of grated cheddar cheese, and fresh cilantro leaves.

Step 12

Serve immediately and enjoy your high-protein beef fajitas tacos with a squeeze of additional lime if desired.
