Sprinkle the fish with lemon juice, add salt and pepper and place in a pan.
Peel half the tomatoes, grate them, add the tomato paste (thinned in a bit
of water), garlic, parsley, olive oil and salt & pepper. Mix and pour over
the fish. Slice the rest of the tomatoes in thick slices, place them over
the fish and top with the bread crumbs. Bake in medium oven for about 40
minutes.
