How to make
Peel the onions, wash and cut into wide circles. Remove the first and third circle, then the second with the fourth. They need to be grouped in one so that there is room for the yellow cheese, which we will put in the middle.
The mozzarella cut into strips as wide as the onions.
Grab take the first circle and put the third one inside it. Between them, stuff with cheese strips. Arrange all the circles in a tray and leave them in the freezer for a while.
Beat the eggs with a wire whisk. In two plates put the flour and breadcrumbs separately.
Remove the onions from the freezer. Dip them first in flour, then in egg, breadcrumbs, egg and again in breadcrumbs.
Fry the stuffed onions in very hot fat.
The stuffed onions with mozzarella are ready.
