I am cooking my first turkey ever, and am confused about how big a bird to get. There will be five of us. I've looked at various turkey websites, and they suggest 1 lb. per person, which would give us a 5 lb. bird. Most of the recipes I've seen start with a 12 lb. turkey at a minimum. We'd like enough for Thanksgiving and maybe 2 sandwiches per person afterwards, but not turkey for days. How big a bird should I order?
