Years ago my mother used to make shepherd's pie. We were thinking of having it again for christmas dinner, but nobody can remember where the recipe was from, and since my parents are moving in early Jan, most of the cookbooks are packed up. I think it may have been from one of the Silver Palate cookbooks... and I'm pretty sure it called for grated (cheddar?) cheese to be mixed in with the mashed potatoes... Anybody have any ideas, or a good recipe of your own?
