Start by making the marinara (recipe below). While the sauce is simmering, start the chicken.
Beat the egg with a fork in a shallow bowl and set aside.
Pour the gluten free flour into another flat bowl. Crush your crackers in a Vitamix or put the crackers in a Ziploc and use a rolling pin to crush them fine. Set in a shallow bowl. Add to the bowl the almond flour, salt, and pepper.
Dry each piece and place one at a time on a cutting board with cellophane or parchment over and pound to flatten slightly and tenderize each piece. Add a tiny bit of salt and pepper to the top of the chicken pieces. Taking one piece at a time, coat each side of chicken with the gluten free flour. Next dip in the beaten egg to coat each side, and finally coat each side in the cracker mixture. Remove to a large plate. Continue with remaining chicken pieces.
Preheat the oven to 400 degrees F. Heat a skillet over high heat. Add oil and heat. Place each chicken piece into the skillet, two at a time, and cook for 2 minutes before turning over with a spatula. Cook for 2 minutes on the other side. Remove to a rectangular casserole dish.
Bake for 8-12 minutes. Top with marinara sauce, slices of mozzarella, and Parmigiano cheese. Broil for 3-5 minutes until the cheese is golden brown.
Garnish with fresh basil. Serve with gluten free pasta (Le Veneziane Gluten Free Capellini is perfect) topped with marinara sauce and additional Parmigiano Reggiano or parmesan cheese.
