Take the eggplants and the courgettes, which we wash, wipe and cut into cubes, without peeling them. The peppers, after I washed them, I cut them in half, and I took out their seeds and I cut in cubes. Peel the onions cut them into four and slice them not very thin. Finely chop the garlic, also cut the tomatoes as small as possible.
In a pot, I heated 100 ml of olive oil, in which I fried the eggplants, zucchini and peppers cut into cubes. Fry them over high heat, about 15-20 minutes, until they get a colour. After we have fried them a little, take them out in a bowl. Clean a little the pot in which the vegetables were fried, put three tablespoons of olive oil to heat, and fry the onion and the garlic. Season with sea salt, freshly ground pepper, and chopped basil.
Fry everything for about 5-10 minutes over low heat, until the onion is golden, then put the fried vegetables back in the pot. Add the chopped tomatoes, canned tomatoes, grated lemon peel and cook for about 30 minutes. Season with a tablespoon of thyme and if you want a little sea salt, and a tablespoon of balsamic vinegar.
