This is healthy change from baked or fried fish. Fresh halibut is a wonderful firm, mild fish and poaching just highlights that. Now if you can't find Halibut, Cod will also work, and if you can't find fresh fish, frozen will be ok. Obviously not as good, but today there is some very good frozen fish on the market. Serve with a quinoa salad and maybe some micro or spring greens for an extremely healthy meal.
