Favorite Potato Nomnoms?

[mermaiden]

As my darling wife pointed out, potatos are incredibly cheap and we're going to try to do acouple of potato type dinners this week, since it's a sort of poor week. I've been doing a bit of Googling, and found some tasty looking dishes, but I was wondering if anyone had some lovely, favorite potato type recipes that they'd like to share that are relatively inexpensive and nutritious?

We're going vegan this week, so we don't yet have vegan cookbooks to help. Any recipe is most appreciated! :)
