Butterfly chicken breast by making a large cut horizontally, making sure not to cut it in half and opening like a book. If you do end up cutting it in half, you can still use it but make a smaller version.
2 chicken breasts
Season chicken breasts lightly with salt. Then place a layer of plastic wrap over them and flatten.
1 tsp salt
Lay chicken breast on top of plastic wrap then add a layer of 2 slices of ham. You want it to cover as much of the chicken as possible. Then place two slices of mozzarella cheese on top of the ham.
Repeat with another layer of ham and cheese.
Roll everything up tightly using the help of the plastic wrap to make it extra tight. Then place in fridge for 30 minutes.
Roll in flour, then into egg wash, and finally coat in panko bread crumbs.
½ cup flour, 2 large eggs, 1 cup panko
After your chicken has been tightly coated, poke 4 toothpicks into the chicken breast to prevent it from unravelling during the cooking process.
8 toothpicks
Fry at 350F for 5-8 minutes until golden brown. Season immediately with salt
