Pound the chicken breasts to a thickness of ¼ inch.
Season both sides lightly with salt.
Whisk the eggs in a small bowl.
In a separate bowl, combine parmesan cheese, garlic powder, onion powder, and any leftover almond flour.
Dip each chicken piece into the whisked eggs, allowing the excess to drip off.
Coat the chicken in the parmesan-almond mixture.
Heat oil in a non-stick pan and fry the chicken for 2-3 minutes on one side until golden.
Flip and cook the other side for an additional 3 minutes.
Remove the chicken from the pan and place it on a paper towel-lined plate to absorb excess oil.
Preheat the oven to 200°C (400°F) and line a large baking sheet with parchment paper.
Arrange the fried chicken on the prepared baking sheet.
Spread marinara sauce over each piece and top with 2-3 slices of mozzarella and 2 tablespoons of parmesan cheese.
Bake the chicken for 10-15 minutes, or until the cheese is melted and slightly golden.
Remove from the oven and serve immediately.
