Remove the stalk from the mushrooms and cut into small pieces. Chop the parsley. Peel and press the garlic. Mix the ingredients with the breadcrumbs and the parmesan. Pour the mixture into the mushrooms and drizzle with olive oil. Bake in the oven at 200 ° C for about 15 minutes or at least until the mushrooms are browned. A fresh, green salad tastes good with it.
