Roasted beets are delicious and easy to make. They go well with salads, meat, and alone as a quick snack. Just add a little olive oil, salt and a squeeze of lemon.
Poaching fish in olive oil gives it a luxe texture. Don't think the fish is going to be oily or greasy as a result because it's not. In fact, poaching --the gentlest form of cooking-- gives the fish a terrific, clean flavor. Halibut is fairly bland, so it needs the flavor intensity that the beets and blood oranges supply.
