Preheat the oven to 450 degrees F. Choose an oven-proof baking dish that your fish will fit in without overlapping and spray it with cooking spray.
Lay the fish fillets in the baking pan in a single layer, season with salt and pepper, then top the fish with red onion and bell pepper.
Sprinkle with dried basil and oregano, the tomato, and the feta cheese, then drizzle the white wine and olive oil over top. Grind some fresh pepper over the top.
Bake uncovered for about 12 – 15 minutes or until the fish flakes easily with a fork. Squeeze the lemon wedges over the cooked fish, garnish with the fresh basil and/or oregano and serve with hot cooked rice.
