As I wanted an all in one meal for four, I chose to layer and cook it on a cookie sheet. If you don't want to ruin the finish on your baking sheet, line it with either parchment paper or aluminum foil. Then spray with Pam or oil so nothing sticks.
This was quick and easy and had lots of flavour. The combinations of vegetables and seasonings you can explore with this technique are endless, so be sure and throw caution to the wind and be brave. You may invent your family's next favourite dish. One of my sons is picky about his vegetables. He won't each broccoli and cauliflower, but likes asparagus - go figure. So that's the direction I took. I think homemade pesto is better, but had no time to make it. Store bought filled in just fine. I also loved the fact you could adjust this to serve any number of people. I could have done 3, 5 or 6 with little effort.
