My family's favorite salmon fillets are cooked in foil.
I oil the fish on all sides so that it doesn't stick to the foil.
Black pepper, garlic, dill, onion slices, lemon slices, butter.
I grill (or bake) until almost done, then open the foil to lightly brown the top while it finishes cooking.
This is overcooked by many peoples standards, but it is the only way my wife and kids will eat it!
