Bacon, egg, and potato casserole! A couple of things though: the recipe needs more bacon and I'd likely use frozen hashbrowns instead of diced potatoes. I'd also leave out the sun-dried tomatoes. But that's just me. :)
This Thanksgiving Sandwich version steps its game up with cheese and bacon, but there is nothing wrong with keeping is "simple:" bread+mayo+stuffing+mashed potatoes+cranberry sauce+turkey+bread. You can add lettuce if you must.
FROM MyFridgeFood.com: Mashed Potato Puffs. Sounds like a great way to use up leftover mashed potatoes.
