With the coming of fall, the truck farmers are rolling out the pumpkins, and happily, so are the chefs. Soup to nuts, or at least seeds, pumpkin and its squash cousins are among the great sweet treats, even without that evil pie crust. And as it happens, October is World Vegetarian Awareness Month, so you can indulge yourself and pretend to be getting into the health swing at the same time. Here are some of the dishes popping up on Washington menus:
