Simple Baked Fish with Tomatoes

Heat your oven to 400°F. In a glass baking dish, whisk together the olive oil and lemon juice.

Place the fish fillets in the dish and turn them once to coat both sides with the oil mixture.

Season the fish with salt, pepper, and basil. Layer the tomato and onion slices over each fillet in a single layer.

Sprinkle the Parmesan cheese over everything. Cover tightly with foil and bake for 15 minutes, or until the fish flakes easily with a fork.
