How do I roast vegetables?
user
It's best to roast vegetables in a preheated oven.  You can either cook the vegetables directly in the oven or place them on a baking tray and cook them under a broiler.  When roasting vegetables, it's important that they be at least partially cooked before placing in the oven.

Sorry, I don’t really know what that is.  What do you mean?  Can you give me an example?
