Asparagus with Orange and Hazelnuts

I made this vegetable dish back last November, but with fresh asparagus starting to show up in the stores again it seemed like a good idea to post it now. Fresh asparagus is great just steamed with a little lemon juice squeezed on at the end, but how many times can you eat it that way. The simple addition of some grated orange zest, juice, and a few chopped hazelnuts wasn't much work, but added flavor and made the dish seem more special. If you don't mind the added fat and calories, go for the butter too. Page 250
