Oven Bake dChicken Fajitas for a Crowd

Oven Baked Chicken Fajitas

This is an easy to make baked chicken fajitas recipe. This recipe is better most fajitas I've had in Mexican restaurants. The recipe makes a lot of food! If you are feeding a small family, you may want to half it. If you half the recipe, remember to half the spices too! For a less spicy version, leave out the jalapeno peppers, and cayenne powder.
