Preheat the oven to 400 F.
Prep your vegetables. Chop everything into bite-sized pieces. Everything will be cooking at the same time, so harder vegetables should be cut into smaller pieces to cook through together.
At this point, I throw everything into the biggest bowl I have or into a big ziplock bag. Pour in the olive oil and generous amounts of salt, pepper and spices. Toss and turn the veggies to coat them well, and then pour out onto a sheet or roasting pan.
Stick this in the oven for 30-45 minutes (or until everything is well roasted). Depending on how much you made, you may have to take it out to toss around the vegetables a time or two.
It is easy to add meat to this recipe. Growing up, we always put chunks of sausage on top, but chicken works just as well. Be careful with the amount you make. It's easy to make entirely too much which results in soggy vegetables that are too much of a hassle to cook. And you can always do the chopping ahead of time so that this dish pulls together completely in under an hour!
