Preheat the oven to 425F or 400F convection. Line two rimmed baking sheets with parchment paper.
In a medium pot, add the quinoa and 1 ½ cups of water. Bring to a boil, then reduce the heat to low and simmer, covered, for 15 minutes, or until the water is absorbed. Let sit for 5 minutes, then fluff it up with a fork and set aside.
Add the carrots to one half of one baking sheet, and cabbage to the other half. Add the chickpeas to the second baking sheet. Use a kitchen towel to dry the chickpeas off a bit. Drizzle the carrots and cabbage with 2 tablespoons of oil and the chickpeas with 1 tablespoon of oil. Sprinkle each baking sheet with ½ teaspoon salt. Toss everything separately to coat.
Bake for 15-20 minutes, or until the vegetables are golden/charred in spots and the chickpeas are starting to turn golden. The chickpeas may be done sooner than the vegetables.
Make the dressing by adding all ingredients to a jar with a tight-fitting lid. Shake vigorously to combine.
Add quinoa, roasted veggies, chickpeas, and chopped apple or pear to your bowl. Drizzle generously with the maple dijon dressing and top with toasted pecans or walnuts and herbs.
