It's the dish everyone's expecting on the holidays, but it's so easy to make, you can serve it any day. What makes our green bean casserole so good? A secret ingredient - cream of mushroom soup.
No-boil lasagna noodles are perfect for this recipe, as they absorb all the juices that accumulate in the crockpot. Use 2 (10-ounce) packages of frozen chopped spinach in place of fresh, if you prefer. Also, any mushroom will work.
