To go along with Grace...did you know that you can also keep your stuffing and mashed potatoes in your crockpot???? They will be nice and toasty warm, not dried out, and are the yummiest way to do them especially for large group meals! I discovered this at Thanksgiving time with my Moms' Group at Church! I'd have never thought of it...but it works amazingly well!
I also will make a "casserole" in my crockpot...especially when using already cooked meat for said casserole...just dump all the cooked ingredients (best for noodle or potato dishes like good ol' tuna noodle casserole) into your crockpot, and set it to Low, and let it "cook" the rest of the day until you're ready to eat!
I've also made soups galore in there...simply dump all the ingredients into the crockpot, and turn it to high til it boils, and then turn it to low to simmer the rest of the day/overnight, whatever...fantastic for taking meals to potluck dinners, or when providing meals to folks that have just had surgery or whatever.
