Commentary:
This is a new twist on a classic summer garden vegetable dish, healthy and with a good combination of flavors. I made this with pattypan squash for the summer squash. Never cooked with them before - they taste just like yellow summer squash but look sort of like flying saucers (cute, huh?). I cut them in half horizontally so they still look attractive but aren't such big chunks. Essentially the sausage is for flavoring. I would substitute 4 cups of just about any vegetables in this dish. I see this as the kind of dish you make for using up the vegetables you have. It would be good with mushrooms, too.
I like to cook with pesto a lot - quick way to get exceptional flavor, and it always goes well with chiles. This is the kind of recipe I use as a guideline rather than sticking to exactly.
