If using fresh peas, blanch 2 minutes in boiling salted water. Remove with a slotted spoon and plunge into an ice bath to cool. Drain and dry. If using frozen, let them thaw in a colander and dry.
Preheat oven to 425 degrees.
In a large bowl, combine all ingredients. Toss to mix well. Spread onto an oiled jelly-roll pan and roast 8 minutes. Turn veggies with a spatula and roast another 6 minutes. Serve hot.
