Is it a vegetable or a dessert?

I don't know. But we like it. Okay...we devour it!

1 small butternut squash, about 2 pounds
2 apples, cored, peeled, sliced then chunked
about 1/4 cup butter
salt to taste
1/2 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
brown sugar sprinkled to your liking on top of it all

Peel squash, scoop out seeds, and cut in small pieces.
Place squash and apple slices in baking dish , one night it was in the oven and the next time it was in a glass corning ware with a lid.
I have a mixture of cinnamon, nutmeg and regular sugar in a shaker for cinnamon toast. I usually use that liberally on top of the squash and apples. Add bits of butter all over the squash/apples/seasonings. Then top with the brown sugar. Be brave you can do it!
Bake butternut squash casserole at 400° for about 25 to 30 minutes or in the microwave cover and cook until cooked to a mashable consistency. (DON"T MASH) Oven results produces a syrup glaze ... Microwave not so, still tastes awesome.

If you don't like taking on a squash to cut and chop- go to Costco and get the butternut squash already chopped ready to use. If you are really short of time they even have apples cored and sliced and all you have to do is chunk those.
