Baked Fish with Tomato and Onion (Psari Plaki)

Preheat oven to 350F. Heat 2 Tbs oil in a heavy-based frying pan. Add the onion, celery and carrot and cook over low heat for 10 minutes or until soft. Add the garlic, cook for 2 minutes, then add the chopped tomato, passata, oregano and sugar. Simmer for about 10 minutes, stirring occasionally, until reduced and thickened. Arrange the fish in a single layer in a baking dish. Stir the chopped parsley and the lemon juice into the sauce. Season to taste and pour over the fish. Scatter the breadcrumbs all over the top and drizzle with the remaining oil. Bake for 20 minutes, or until the fish is just cooked.
