Cut the eggplant in slices, about 1/4 inch thick. Slices should be cut long way.
Tomato Sauce: in a saucepan put some EV olive oil and add the finely chopped onion. Once the onion is slightly golden add the tomatoes. Cook at low flame for 20 minutes. Stir the content from time to time.
Stuffing Preparation: in a mixing bowl, add the eggs, Parmigiano (leave a bit to put on the eggplants at the end), bread crumbs, chopped garlic, chopped parsley, chopped mint, 2 Tbs of olive oil and the mozzarella cut into cubes. Mix everything well.
Take each slice of eggplant and add 2 tablespoons of stuffing on the slice and roll it. Repeat the process for all the slices of eggplant.
In an oven pan, first add a layer of sauce and then place all the rolled eggplants.
