First fry the minced meat in a little oil in a large saucepan. When the minced meat is well done, add the zucchini cut into pieces over a low heat until it is a little soft (not too soft!). Then add the drained mushrooms and the pizza tomatoes. Season the whole thing with pepper, salt and herbs.
Put the gnocchi in a baking dish and spread the minced meat and vegetable sauce evenly over it. Now sprinkle the cheese over it and put it in the preheated oven at approx. 200 ° C top / bottom heat for 25-30 minutes.
