Tips: If using fresh bread, you can grill the bread slices along with the salmon and then cut them into cubes. Alternatively, cut bread into cubes, place on a baking sheet and bake at 300°F until dry.
How to skin a salmon fillet: Place salmon fillet on a clean cutting board, skin-side down. Starting at the tail end, slip the blade of a long knife between the fish flesh and the skin, holding down firmly with your other hand. Gently push the blade along at a 30° angle, separating the fillet from the skin without cutting through either.
To oil the grill rack, oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.) When grilling delicate foods like tofu and fish, it is helpful to spray the food with cooking spray before placing it on the grill.
