Cut onions into rings, fry in olive oil with pressed garlic.
Salt and pepper fish fillets, put a half in greased mold, put over fried onion with garlic, scatter over tomato and lemon slices and cover with the remaining fish. Scatter over butter slices and bake over 390°F until done.
Garnish the fish with cooked rice and eggplants and cucumbers, fried with dill in butter.
