Shape the dumpling dough like a pizza, press it flat and place on a baking sheet lined with baking paper or grease the baking sheet lightly (I prefer that because it is difficult to remove the dumpling dough from the baking paper).
Brush the dumpling dough with the tomato sauce and top it if you like. Sprinkle with cheese and put the pizza in the preheated oven for about 15 minutes at 200 ° C.
