Filling
White Sauce
Start by cutting three chicken breasts - make a shallow cut right in the center of each chicken breast.
Coat the chicken breasts in the wheat flour, next, dip them in the beaten eggs, coat them in the Panko breadcrumbs and set aside.
To prepare the filling, arrange 3 slices of bologna in a row.
Add 1 slice of mozzarella cheese on top of these slices, then add 3 more slices of bologna and, finally, another slice of mozzarella cheese.
Next, cut into 3 equal sized strips, put them all together and repeat this process 2 more times.
Place the chicken breasts in a baking tray lined with parchment paper.
In a large skillet over medium to low heat, add the unsalted butter and stir until fully melted.
Add the wheat flour and stir until combined.
Then, add the milk at room temperature and stir until smooth and slightly thickened.
Season with the salt and stir until combined.
Place the slices of bologna and mozzarella cheese we prepared earlier into the breaded chicken.
Drizzle each of them with the white sauce we made and add 50g of grated mozzarella cheese on top of each chicken breast.
Take to a preheated oven at 180 ° C (350 ° F) and bake everything for 45 minutes.
Serve.
