We do lots of soups and stews in the cooler months. "The Voluptuous Vegan" (Myra Kornfeld) is one of our favorite cookbooks. The food is real (no processed or pre-fab ingredients or TVP/TSP). Just thinking about the chickpea crepes makes my mouth water! The recipes can be pretty time-intensive; but in chilly weather, that's a plus.
And, of course, if you have a pressure cooker (doesn't everyone?!), you can't go wrong with pretty much anything by Lorna Sass.
