Preheat your oven to 350 degrees F and lightly grease your baking dish/dishes with avocado oils spray (I usually need 2 dishes for 6 chicken breasts).
In a shallow bowl, combine almond flour, tapioca flour, Italian seasoning, onion powder, garlic powder, salt, and pepper. In a shallow dish add your beaten eggs.
Pat your chicken breast dry and dredge each chicken breast first in the egg mixture and then in the flour mixture until evenly coated. Then set aside.
In a large skillet heat the avocado oil over medium high heat. Cook the chicken breasts for 3-4 minutes on each side or until golden brown and place in baking dish.
Top each chicken breast with 2 tablespoons of marinara sauce and place uncovered in the pre-heated oven. Bake for 20 minutes or until chicken is cooked through (I check with a meat thermometer to make sure it reaches 165 degrees F).
Add fresh chopped basil and if you wish some cheese. Serve with your favorite veggies, pasta, or potatoes.
