Preheat oven to 400 F.
In a bowl, combine the cheese stuffing ingredients together. Set aside.
In 3 other separate bowls, whisk the egg in one, place the bread crumb in another and the 3rd mix in the flour mixture ingredients together.
Slice each chicken breast in half horizontally to get 2 pieces from each, 4 total.
Place each slice of chicken between a saran wrap sheet and pound the chicken a couple of times to even it out.
place a scoop of stuffing onto the chicken slice and spread out.
Roll the chicken and and tuck the sides well so the cheese mixture does not ooze out much when baking. Secure the bottom with toothpick. Repeat for the remainder of the chicken pieces.
Coat each piece with the flour mixture, then the egg mixture and then finally coat well to cover all the areas with the bread crumb.
Place on a baking dish lined with parchment paper and spray generously with olive oil spray.
Bake in the preheated oven for 20 minutes or until the chickens flesh temperature (not the filling inside) reaches 150 F. You can use an instant read thermometer to do that.
Remove from the oven and let the chicken rest for a few minutes before serving.
