A friend of mine gave me this recipe that she says is a huge hit at her Thanksgiving. I'm planning to make it.
Saute one chopped white onion and 1 lb. sliced yellow squash in one stick of butter. Combine with 3x 15 oz. cans hominy (drained), 1 lb. cubed pepper jack, 1 tsp salt. and 1 pt. sour cream. Top with 1/2 lb. shredded cheddar and bake at 350 for 1 hour.
I also make a sweet potato casserole that's basically a dessert (and treated as such). It's really very good.
