Meal Prep Steak Fajitas are tender, juicy and full of flavor! Best of all, they come together super quick and are perfect for busy weeknights.
Combine all the ingredients for the homemade seasoning. Reserve 1 1/2 teaspoons for the bell peppers.
In a large resealable bag, combine 2 tablespoons of olive oil, lime juice, mustard and 5 teaspoons of the fajita seasonings. Add the steak, and press the bag in to evenly distribute the flavors. Allow to sit while you prepare the vegetables.
Prepare the bell peppers and onions by slicing into thin strips.
Heat 1 tablespoon olive oil in a large pan over medium-high heat. Add the onions and allow to cook for about 3-4 minutes, or until softened and fragrant. Add the bell peppers and sprinkle with the reserved 1 1/2 teaspoons of fajita seasonings. If you like the peppers with a nice crunch - cook for about 3-5 minutes. And if you like them softer, leave them on for about 3 minutes longer. Transfer and set aside on a plate.
Serve hot with heated tortillas, avocado slices and lime wedges plus any other toppings of your choice.
For a low carb version, you can use coconut wraps, low carb tortillas or serve over some lettuce or cauliflower rice.
