Preheat oven to 400 F. Line a baking sheet with parchment paper, lightly spray with cooking spray, set Aside.
In a small mixing bowl, whisk together eggs, garlic powder, and parsley, and just a bit of salt and pepper - a pinch each.
Add chicken pieces to the egg mixture, stirring to coat. Set aside for a few minutes to marinate a little. (You can cover and chill for a few hours, if you’d like)
Heat a bit of oil in a large, nonstick pan - about ½ - 1 cm deep.
As oil heats, mix together almond flour, whey protein isolate, parmesan cheese, garlic powder, salt, and pepper in a medium bowl.
Dredge each chicken half in this coating mix, pressing to evenly coat the whole surface of each.
Fry chicken for a few minutes on each side, until golden brown and crispy. Remove from oil, transfer to the prepared baking sheet.
Top each piece with half of the sauce, then half the mozzarella cheese, and half the parmesan cheese.
Bake for 15 minutes, or until chicken is cooked through.
Top with fresh basil, serve immediately.
