For the liver cheese pizza, place the slices of liver cheese in a baking dish and spread each slice with tomato paste. Now wash the zucchini, cut 16 thin slices and place them on top of the tomato paste.
Salt the zucchini slices a little. Peel the onion and cut it into thin slices as well, which are placed on top of the zucchini.
Wash the cherry tomatoes, cut them into small pieces and place them on the onion slices. Finally, cover each slice of liver cheese with cheese and sprinkle with thyme, some salt and garlic.
Bake in the oven at 190 degrees for about 15-20 minutes.
