Prepare grill or broiler.
Combine the wine and oil; brush inside and outside of fish. Sprinkle the insides evenly with salt, pepper, onions, and fresh herbs.
Place the fish, skin side down, on grill rack or broiler pan coated with cooking spray, and cook for 5 minutes or until the fish flakes easily when tested with a fork. Serve with lemon wedges.
This is really great, easy to make, excellent for grilling and the taste is fantastic!
