Preheat oven to 400 degrees F.
Line a baking sheet with foil and brush foil with olive oil.
Cut the chicken breasts in half (butterfly the chicken) and slice into 2 pieces.
After cutting all chicken, place chicken in ziplock bag and pound the chicken breasts (with a meat pounder) to an even thickness.
Pat the chicken breasts with a dry paper towel, then season with salt and pepper.
In a shallow dish, mix together panko bread crumbs, parmesan cheese, salt, pepper, garlic powder, oregano, and black pepper.
In another shallow dish, whisk the eggs.
Dip one chicken breast into the egg, then into the bread crumb mixture. Make sure chicken breast is fully coated in the crumb mixture and gently press your hand to help the crumbs stick to the chicken.
Place chicken breast on prepared baking sheet and repeat with remaining pieces of chicken.
Place baking sheet in the oven and bake for 15 minutes (or until cooked through).
Flip the chicken and pour an even amount of marinara sauce over each piece of chicken.
Top each chicken with shredded mozzarella cheese.
Place back in the oven and turn on broiler on high for 2-4 minutes until the cheese is melted and bubbly and edges of chicken are browning.
Serve with pasta.
ENJOY!
