Lay the sliced peppers and onions on the bottom of a baking dish.
Sprinkle the vegetables with ½ tablespoon of taco or fajita seasoning over the vegetables. Drizzle with olive oil.
Place the chicken cutlets on top of vegetables.
Sprinkle the chicken with 1 Tablespoon of taco or fajita seasoning and then top with the shredded cheese.
Bake for 35-40 minutes, or until the chicken is cooked to 165 F when tested with a digital meat thermometer.
Garnish with your favorite fajita toppings and enjoy!
Notes
You can purchase chicken cutlets instead of cutting chicken breasts lengthwise which saves time, however, sometimes the precut chicken cutlets are packaged in varying sizes.To keep this dish keto friendly and low carb, use sugar-free taco seasoning or make our homemade no-sugar taco seasoning. Also, be sure to slice the cheddar from a block of cheese since pre-shredded cheese contains starch (and hidden carbs). The dish can be lightened by cutting back on the amount of cheese used in the recipe.
