When you put vegetables in the oven to roast, they will caramelize. I don’t know about you, but I think that roasting them tastes a lot better than simply steaming. They are also sweeter after being roasted! Anytime you get more vegetables in your system, the better. Roasting vegetables is a huge time saver! We all could use opportunities where we can get something else done! If you choose to dry roast the vegetables with no oil, you will bring down the caloric content of the dish a little. You may lose a little bit of flavor, but once you try it a couple times, it is easy to get used to. Try cutting back on the oil a little at a time until you are roasting with no oil at all. Take a couple of weeks to work through this and you will be pleasantly surprised with the results! Of course, the oil also helps prevent sticking.
