I just got back from Jamaica where I watched a woman make a simple "steamed ginger fish" which was fantastic. She used snapper but I'm sure it would be great with salmon. Basically, throw some oil and butter in a pan and cook some thinly sliced carrots, onions and zucchini- or whatever veg you'd like- for a couple of minutes. Add in a good pile of minced garlic and ginger and some sliced hot peppers, and cook another minute. Add your seasoned pieces of fish, a few sprigs of fresh thyme, and a couple cups of coconut milk. Simmer covered for ten minutes or so, and then adjust seasoning.
