thanks consuelo. i should have thought of doing that before i posted my recipe, but here it is for those looking for it:
SALMON IN FOIL
tear off a large peice of tinfoil, spray the foil with cooking oil (ie PAM) where the fish will touch it and lay your salmon on it in the middle; use either butter (the real thing) or olive oil smeared on the inside (about 2 Tbsp); salt & pepper and add your citrus slices. fold the edges of the tinfoil over using a locking seal and pop into the oven or on the bbq. bake 30 - 35 min @ 350F per inch of thinkness (at the thickest part). remove from oven and let rest no longer than 10 min. take out of foil. i just slide it out of the envelope onto a platter. editted to add: come to think of it probably any citrus fruit would be good, i've used oranges too.
