We are making a few of these squash casseroles and freezing them.  We love freezer meals and having a vegetable casserole in the freezer would be a treat this winter when the garden is gone.   A bubbling pan of summer squash would go well with our Thanksgiving Turkey or our Christmas Baked Ham with Pineapple Glaze.
