01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Toss diced sweet potatoes and red onion with 2 tablespoons olive oil, ground cumin, smoked paprika, salt, and pepper. Spread mixture evenly on the prepared baking sheet.
03 - Roast in the preheated oven for 25 to 30 minutes, stirring once halfway through, until sweet potatoes are golden brown and tender.
04 - Meanwhile, rinse quinoa under cold water. In a medium saucepan, combine quinoa and 2 cups water. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until water is absorbed. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
05 - In a small bowl, whisk together tahini, lemon juice, extra-virgin olive oil, minced garlic, maple syrup or honey, water, salt, and pepper until smooth. Adjust water to achieve desired consistency.
06 - In a large bowl, combine cooked quinoa, roasted sweet potatoes and onions, baby spinach, and chopped parsley. Drizzle dressing over and toss to combine evenly.
07 - Serve the salad warm, garnished with pomegranate seeds if desired.
