Preheat the oven to 375 degrees F.
Chop the sweet potato into ½” cubes (I leave the peel on).
Spread the sweet potato chunks on a baking sheet and drizzle them with enough olive oil to coat them. Sprinkle salt and pepper over everything.
Roast in the oven for 30 minutes or until the sweet potato is cooked through and slightly crispy on the outside.
While the sweet potato is roasting, bring 4 cups of water to a boil and add the quinoa. Return to a full boil, then immediately reduce the heat to a simmer, cover, and cook until all of the water is absorbed, about 15 minutes. Fluff quinoa with a fork.
Whisk together all of the ingredients for the maple-orange dressing in a small bowl.
In a large serving bowl, add the cooked quinoa and pour all of the maple-orange dressing over the quinoa. Toss together.
Add the remaining salad ingredients and toss everything together.
Consume the best quinoa salad ever.
