Cut the steak and schnitzel into thin strips, crumble the minced meat. Cut the onions into rings and dice the peppers. Clean the mushrooms and cut into slices.
Catch the juice of the tomatoes, cut the tomatoes a little smaller. Mix the juice with the pureed tomatoes and season well. Layer the vegetables and meat alternately in a roasting pan, season with salt and pepper after each layer. Pour tomato sauce over it. Place herbs on top of the stew. Cover and cook in the oven for 3 hours at 170 degrees.
Remove herbs afterwards.
In addition, bread, fresh potatoes or rice at lunchtime are enough at the party.
