If you didn’t ask the fish monger to slice the salmon into scallops (LONG SLICES) then do it yourself by placing a carving knife at a 45 degree angle and slice down through the raw salmon to the skin but NOT through it.
Now place your knife at a 45 degree angle& remove the scallops from the skin; discard the skin.
Place the scallops on a plate& cut each long slice into 2 inch pieces.
Heat oil in nonstick skillet.
Season salmon& place flesh side down; fry 1 side only for 1 minute or until browned.
Flip salmon onto baking sheet, browned side up.
Spread some salsa on top of salmon.
Bake in preheated 450F oven for 1 or 2 minutes – just until white juices begin to appear.
