I have to admit that I hate turning on the oven as much as the next person during the warmest months of the year. But my favorite way to prepare just about any vegetable during the summer is to roast them. I just can't help myself. And since I don't have a BBQ (or a back yard to use one in), I inevitably end up turning on the oven again and again to enjoy, in particular, the wonderful array of summer squashes.
