Preheat oven to 375 and mist a 9” x 13” baking dish with nonfat cooking spray.

Using a meat mallet, flatten each chicken fillet to about 1/3” thick. Season both sides with salt and pepper.

Spread 1 tbsp of pizza sauce on one side of the chicken. One on half of the sauced side, lay 1 slice (0.5oz) of the mozzarella cheese, and 8 slices of the turkey pepperoni. Fold the chicken fillet in half, being careful to try and keep the filling inside and rolling in the edges, if possible. Seal with toothpicks, if needed.

Prepare the dredging station by placing the flour in one shallow bowl, the liquid egg whites in another, and the Panko, garlic powder, Italian seasoning, and additional salt and pepper in the third.

One by one, coat each piece of chicken in the flour, then the egg then the Panko seasoning mixture. Be careful to try and can keep the open side of the pocket pinched closed and keep the fillings in (this is why I recommend the toothpicks in Step 3). Place in a prepared baking dish, and bake, uncovered for about 25-30 minutes, or until chicken is fully cooked through and the outside is golden brown and crispy.

Pour the remaining pizza sauce over the chicken right after it is removed from the oven, and serve.
