Wash the zucchini, peel it (the raw one is not needed, but I did this), cut the slices, drain. Place the slices in a bowl and add salt and pepper to taste. In separate plates I put flour mixed with a little oregano and in another well beaten egg (optional salt) with sweet milk.
I proceeded as follows: I took each round, I passed it through flour-egg-flour. Meanwhile, I put a frying pan with hot oil, when it warmed up well, add the slices. Leave one minute (maximum) on each side and take them out on absorbent paper. I served it with sour cream and garlic.
