: Preheat oven to 425 degrees Fahrenheit. Grease a baking sheet. Spread sweet potatoes and red onion on a baking sheet and bake for 18 to 20 minutes.; Place quinoa in a small pot and add half a cup hot water. Bring to a boil, lower heat, and cover until water is absorbed. I usually use one and a half times water to quinoa, but when I cook small quantities, I use more, otherwise the water will get all absorbed before the grain has had a chance to finish cooking (same with rice).; Whisk together dressing ingredients.; Add greens to a bowl. Top with quinoa, sweet potatoes, red onion, and sunflower seeds. Drizzle dressing over everything and toss to combine well. It might not seem like a lot of dressing, but it will get everywhere and flavor everything.; Credits:
