We make meatballs (I got 20 pieces), put a piece of mushrooms in the middle of each.
Fry meatballs until golden brown. Preheat oven to 200°C.
For the sauce: Fry the onion, add mushrooms or mushroom crumbs. Frozen mushrooms will immediately release juice. Simmer it for 5 minutes, stirring. Add cream, salt, bring to a boil. Cut the cheese into pieces, add, stir. At the end put the garlic. Remove from fire.
Arrange meatballs in a refractory form, pour sauce and bake for 20-25 minutes.
