Sheet Pan Fajitas take less than 30 minutes from start to finish and can be made with chicken, steak or both.
Preheat oven to 450 degrees F.
Cut chicken breasts and steak into small slices, against the grain.
Cook for 10 to 20 minutes or until desired doneness. The thin slices of the meat and veggies will cook quickly. Check oven and stir once or twice.
