Preheat the oven to 400 degrees F.
In a large bowl, toss the vegetables with the olive oil, white wine, rosemary, salt, and pepper to coat.
Spread the vegetables in a large baking dish (or two) in a single layer.
Roast the vegetables for 45-50 minutes, stirring every 15 minutes, until they are tender and lightly browned, and the wine is evaporated.
Adjust the seasonings to taste
