Pasta Inverno (Winter Vegetable Pasta)
Use acorn, hubbard, or butternut, but not spaghetti, squash. Frozen chopped spinach can be substituted for the fresh if desired. Two fresh tomatoes can be substituted for the canned tomatoes.
Putanesca additions of pine nuts, artichoke hearts, and such are lovely, but not necessary. It's really like a primavera with winter vegetables, so use whatever you happen to have on hand.
