Fajita chicken is a staple at my house. I use it in fajitas, tacos, on salads, as a protein main with other veggies such as green beans or squash and zucchini... you could even top a potato with it and other 'fajita' toppings for a tasty meal higher in carbohydrates. It's pretty versatile. Quick and simple, just like I like it!
NOTE: If you have a George Foreman grill or similar you can simply season the meat and put it on the grill for a fast salad topper. It is lower in fat this way and not quite as tasty in my opinion but very fast and easy. I do not have a grill at the moment, of any type, so am working on fajita meat on the stove top. This one is just a seasoned meat rather than a marinade but I am working on a marinaded fajita chicken as well.
