The halibut was placed in a foil "bowl" and then I added a home made mustard sauce and topped it with some shredded ginger and dried (no sugar) cranberries. I put 1/3 cup of dried quinoa in a cup of water that was in a baby bread loaf pan.
Started cooking about noon. By the time I brought it in, I had to use pot holders to pick up the pot - it was just as hot as if in an oven.
I let it cook out there for about 3 hours. Both the fish and the quinoa were done to perfection!
