Cook the quinoa according to package directions, and set aside.
Meanwhile, heat the oven to 425 degrees. Prepare the veggies, and mix with the olive oil and spices. Place the carrots and beets on one roasting pan, and the broccoli and cauliflower on the other.
Roast the carrots and beets for 30 minutes, turning once halfway through. Roast the cauliflower and broccoli for 20 minutes, also turning once halfway through.
Plate the salad, top with veggies, quinoa, and your favorite hummus of choice.
