In a large saucepan, combine the broth, rice, Italian seasoning and garlic powder, bring to a boil. Transfer to a greased 11-in. x 7-in. baking dish. Cover and bake at 375° for 10 minutes. Add the broccoli, Parmesan cheese and half of the onions. Top with fish fillets; sprinkle with paprika.

Cover and bake 20-25 minutes longer or until the fish flakes easily with a fork. Uncover; sprinkle with cheddar cheese and remaining onions. Return to the oven for 3 minutes or until cheese is melted.
