Add all of your prepared veggies, chicken, oil and spices to a large bowl. Mix well so everything is evenly coated. Set aside.
2 chicken breasts, 1 red pepper, 1 green pepper, 1 small onion, 2 tablespoons of sweet paprika, 2 tablespoon of chili powder, 1 tablespoon of cumin, 1 teaspoon garlic powder, 1 tablespoon kosher salt, ⅛ cup vegetable oil
Pre-heat your oven to 400 degrees.
Grab a large sheet pan and pour all of the ingredients from the bowl on to your pan, making sure to get all of the spices and oil mixture.
Place in the oven and bake for 10 minutes.
After 10 minutes, give your sheet pan fajitas a quick flip and place back in the oven for another 10-15 minutes or until the chicken is cooked through.
If you want the fajitas more crisped up after cooking, set your oven to broil and place your sheet pan under the broiler for about 3-5 minutes or until there is some light browning on the edges then remove from oven.
Serve with your toppings and tortillas (or with a salad or rice if you are not using tortillas).
8 small flour tortillas, 1 cup queso blanco, 2 lime wedges quartered, sour cream, salsa
This can be made vegetarian as well by just subbing all veggies for the meat. Follow the same steps for cooking.
