Ingredients

• 1 pound Flank steak
• 3 tablespoons Olive oil
• 2 tablespoons Lime juice
• 1 teaspoon Chili powder
• 1 teaspoon Cumin
• 1 teaspoon Garlic powder
• 0.5 teaspoon Smoked paprika
• 0.5 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 Red bell pepper
• 1 Yellow bell pepper
• 1 Green bell pepper
• 1 medium Yellow onion
• 2 tablespoons Butter
• 8 large leaves Butter lettuce leaves
• 2 tablespoons Fresh cilantro
• 0.25 cup Sour cream (optional, for topping)
• 1 Avocado (optional, sliced)

Directions

Step 1

Slice the flank steak into thin strips, cutting against the grain for tenderness.

Step 2

In a small bowl, combine chili powder, cumin, garlic powder, smoked paprika, salt, and pepper. Mix well and rub the seasoning onto the steak strips.

Step 3

Add 1 tablespoon of olive oil and the lime juice to the steak as a marinade. Let it sit for at least 10 minutes while preparing other ingredients.

Step 4

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

Step 5

In a large skillet over medium-high heat, heat the remaining 2 tablespoons of olive oil. Once hot, add the steak strips in a single layer. Cook for 2-3 minutes per side until the steak is browned but still tender. Remove the steak to a plate and cover to keep warm.

Step 6

Reduce the skillet’s heat to medium. Add 2 tablespoons of butter to the pan, then toss in the sliced peppers and onions. Sauté for 5-7 minutes, stirring occasionally, until the vegetables are softened and slightly caramelized.

Step 7

Return the cooked steak to the skillet with the vegetables. Stir everything together and cook for 1 more minute to meld the flavors.

Step 8

Wash and dry the butter lettuce leaves, then arrange them on a serving platter to use as wraps.

Step 9

Spoon the steak and vegetable mixture into the lettuce leaves. Top with fresh cilantro, sour cream, and avocado slices, if desired.

Step 10

Serve immediately and enjoy your keto-friendly steak fajitas!
