This is a yummy, warming casserole that is meant to be a side dish, but since it has meat in it, can also be served as a main dish. This is the version I came up with after significantly reducing some of the heavier ingredients, that were in the original version I saw on Lucy Classic Cajun & Cuisine, a PBS cooking program. But don't let that scare you - this is not a spicy dish at all. I make this often in the end of summer to use up fresh squash. If you don't have both types of squash, just use 2 of whichever type you do have.
