Ingredients

• 1 pound beef skirt steak
• 3 tablespoons olive oil
• 1 large lime
• 1 teaspoon chili powder
• 1 teaspoon ground cumin
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 2 medium sweet bell peppers
• 1 medium onion
• 8 small low carb tortillas
• 0 sea salt
• 0 black pepper
• 1 handful fresh cilantro
• 0.5 cup sour cream
• 1 medium avocado

Directions

Step 1

Start by preparing the marinade. In a small bowl, combine 2 tablespoons olive oil, the juice of 1 lime, chili powder, ground cumin, garlic powder, onion powder, and a pinch of sea salt and black pepper.

Step 2

Place the beef skirt steak in a shallow dish or a resealable plastic bag and pour the marinade over it. Ensure the steak is evenly coated. Marinate for at least 15 minutes, or up to 2 hours if you have extra time in the refrigerator.

Step 3

While the beef is marinating, prepare the vegetables. Slice the sweet bell peppers and the onion into thin strips.

Step 4

In a large skillet, heat the remaining 1 tablespoon of olive oil over medium-high heat. Add the bell peppers and onion to the skillet. Sauté for about 5-7 minutes, or until they're tender and slightly caramelized. Remove the vegetables from the skillet and set aside.

Step 5

Return the skillet to the heat and add the marinated steak. Cook the steak for about 3-4 minutes on each side, or until your desired level of doneness is reached. Remove the steak from the skillet and let it rest on a cutting board for a few minutes.

Step 6

Slice the steak thinly against the grain.

Step 7

To assemble each taco, place a few slices of steak and a portion of the sautéed vegetables onto a low carb tortilla.

Step 8

Garnish each taco with fresh cilantro leaves, a dollop of sour cream, and slices of avocado.

Step 9

Serve the tacos immediately while they are warm and enjoy!
