HOW TO MAKE THESE LOW CARB STEAK FAJITAS Start off by making the homemade fajita seasoning. It’s a blend of chili powder, cumin, smoked paprika, onion powder, garlic powder, salt and black pepper. Combine the olive oil, lime juice, cilantro, mustard and fajita seasonings for the steak marinade.
Slice the the onions and bell peppers. Heat 1 tablespoon olive oil in a 12" skillet over medium high heat. Add the onions and allow to cook for about 5 minutes, or until softened and fragrant. Add the bell peppers and sprinkle with the reserved 1 1/2 teaspoons of fajita seasonings.
Let the fajita meat come to temperature for 30 minutes before cooking. Slice the bell peppers and place into a bowl large enough to accommodate them and the onions from the marinade, but not the crushed garlic. Pour a little oil over the onions and peppers and toss to coat.
