Cut the dumplings into thin slices. Cut the ham, onion, bell pepper and tomato into cubes. Add the glass of cut mushrooms. Mix everything in a bowl and refine with salt and pepper. The mass is placed in a baking dish and sprinkled with cheese. Bake in the oven and at 180 ° C for about 20-30 minutes.
You don`t need to put the Maultaschen in broth beforehand, because the tomatoes make the casserole nice and juicy.
