For venison cutlets, first chop the onion and sauté in a little oil until translucent. Then fry the meat (coarsely diced) so that it is cooked through.
Cut the mushrooms into small pieces and fry them in a separate pan. When the meat is cooked through, deglaze with red wine and add mushrooms, bouillon cubes, salt, pepper and marjoram.
Let it simmer for a short time and then dust with a tablespoon of flour and add water (take the pan off the stove for dusting).
When the meat is soft, the meat is ready.
