In a large bowl, mix all the vegetables with some peanut oil. Put parchment on a half sheet pan and spread the vegetables so they are in a single layer.
Roast them at 350 F / 176 C for about 30 minutes or until the carrots are tender soft. While that is happening, combine the sauce ingredients and set them aside.
Put the roasted vegetables in a large pot and pour the sauce mixture over them. Toss to coat. Serve immediately.
