Place your flounder in a medium baking dish (any dish that it can fit in will work) and place your butter on the fish and season with salt and pepper. Sprinkle your lemon juice on the flounder and top with garlic powder, basil and tomato.
Cover and bake in the oven for 30 minutes. The fish is done when it flakes easily with a fork.
