Preheat oven to 350. Toss the carrots and parsnips with a few tablespoons of olive oil and a few pinches of salt. Spread them on half of a parchment-lined baking sheet. Toss the beets with olive oil and salt and put them on the other half of the lined baking sheet. (Keeping the beets separate from the carrots and parsnips helps to prevent all of your vegetables from turning red from the beets).
Combine the onion and garlic with some olive oil and salt and put them on a separate parchment-lined baking sheet. Put both pans in the oven and roast for about 45 minutes to an hour, or until the root vegetables are tender and the onions are soft. Remove from the oven and let cool slightly.
In the meantime, combine the cooked quinoa, cooked chickpeas, salad greens, cilantro (or parsley), and walnuts in a large bowl. Add the roasted vegetables to the bowl and toss lightly just to combine. Serve on plates or bowls with lots of the delicious honey dijon dressing poured over top.
Dressing
While the vegetables are roasting, combine all of the dressing indredients in a bowl. Wisk until the dressing is emulsified. Alternativeley, add all the dressing ingredients to a small mason jar, screw the lid on tightly, and shake well. Taste the dressing and adjust to your liking (add more mustard, more honey, more olive oil, etc...) Pour the dressing over the finished salad and enjoy!
