2 cod fillets (1/4 lb. each)
1 tbsp. tartar sauce
3 tbsp. seasoned dried bread crumbs
4 tomato slices
1/2 tsp. lemon juice, divided
1/8 tsp. oregano leaves, divided

Preheat oven to 400 degrees. Dip cod fillets in tartar sauce, then dredge in bread crumbs, coating both sides and using all of both ingredients. Arrange fillets on non-stick baking sheet. Arrange tomato slices alongside fillets; sprinkle tomato slices with lemon juice and oregano. Bake until fish is golden and flakes easily when tested with a fork, about 10 minutes. Serve fish with tomato slices.
