I found a Rachel Ray recipe for "turkey chili shepherd's pie with sweet potato & cheddar topping"...

I'm usually iffy with Rachel's recipes. They almost always seem really out there in terms of flavors and ingredients.

But this. This is hella yummy. You mash the sweet potatoes with some nutmeg, sour cream, and o.j. (I leave put the o.j.) & slather it on top and then sprinkle a bunch of cheddar on top and bake.... Sooo yummy.
