The passed tomatoes are boiled together with the hot vegetable stock (fresh or instant, mixed with hot water). Then let cool slightly and puree heavily or lightly, depending on your taste.
Then finely dice the onions, the fresh vegetables and the fresh tomatoes and cut the leek into 0.5 - 1 cm thick slices. Fry the onions in a little butter, now perhaps fry the ham, bacon or the salami. Then add the leek, fresh vegetables and tomatoes and sauté.
Now it is seasoned according to taste. Then thinly slice the mozzarella over the vegetables (over medium heat) so that it melts quickly. Caution: Do not let it burn, if necessary reduce the temperature a little!
Now the vegetables (still over medium heat) are extinguished with the vegetable broth and tomato mixture, which has cooled down a bit in the meantime, then reduce the temperature. Slowly dissolve the creme fraîche in it, season to taste and serve with rice or pasta.
It`s quite a quick and easy recipe and the kids love it, despite the vegetables.
