Combine all ingredients together and then spread onto a rimmed baking pan.
Bake at 425°F for 10 to 15 minutes until vegetables are tender and starting to brown. Toss vegetables at least once during the middle of the baking time for even cooking.
Be sure not to overlap the vegetables. They should be in a single layer for roasting evenly.Florets should be cut to about the same size so smaller pieces don't burn while larger ones are still cooking.
