Preheat your oven to 425 degrees.
Take chicken breasts and place them on a large cutting board. Slice the chicken breasts in half lengthwise creating four cutlets. Cover the cutlets with plastic wrap. Using a meat tenderizer, pound the chicken until about ¼-inch thick. Set aside.
Next, add the flour to a shallow bowl. In another bowl add the eggs and whisk. In a third shallow bowl combine panko, oregano, garlic powder, onion powder, kosher salt, pepper, and parmesan cheese. Take a chicken cutlet and dredge through flour, egg, and then panko mixture. Set aside on a plate and repeat the process with remaining chicken.
Add ¼ cup of olive oil or vegetable oil to a large skillet. Preheat the skillet to medium-high heat. Add two cutlets to the skillet and gently fry on both sides until golden, about 4 to 5 minutes. Remove the chicken from the skillet and place on a plate. Repeat the process with remaining chicken.
Meanwhile, melt the butter in a medium saucepan over medium heat. Stir in the hot sauce. Set aside.
Wipe out the skillet that you fried the chicken in and spray with non-stick cooking spray. Place the chicken back in the skillet and top with buffalo sauce, sliced mozzarella, and parmesan cheese. Cook the chicken in the oven for about 5 to 7 minutes or until the cheese has melted. Serve with more hot sauce and enjoy!
