Lightly oil a baking pan large enough to accommodate the fish. Place salmon in pan skin side down. Run finger over flesh to make sure all bones have been removed. Use pliers to pull out any that remain. Squeeze juice of one lemon and white wine over fish. Lightly salt the salmon. Marinate 15 minutes.
Coat the top side of the fish with thick layer of pesto. It should be between an 1/8th to a 1/4 of an inch thick, and cover the surface of the fish.
Place fish under the broiler. Broil for 8 to 10 minutes per inch of thickness, or until fish flakes and flesh is opaque. Pesto should have formed a heavily browned or even blackened crust.
Remove from the oven, and set aside for a few minutes. Slice remaining lemon half into thin slices. Serve with lemon slices or arrange on the whole flank for presentation.
notes: the size of the salmon can be much bigger or smaller depending on your party size without having to adjust the recipe. I make my pesto a day ahead so I have very little to do the day of the dinner party. I serve it with rice Recipe #191120. Leftovers are great cold on a salad with a light vinaigrette dressing.
