Here's a great way to get all your veggies in, with tons of flavor. I used to make this often when I was a caterer as an alternative entrée for non-meat eaters because it's an elegant dish with lots of colors and textures. It's also quite convenient, because it can be prepared ahead of time, so if you have vegetarian guests at your next gathering, you can assemble this early and then just pop it in the oven while you're making the rest of the dinner. But don't think this is strictly for vegetarians; it's a real crowd-pleaser all around.
