01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Toss diced sweet potatoes and sliced red onion with 2 tablespoons olive oil, ground cumin, smoked paprika, salt, and pepper. Spread evenly on the prepared baking sheet.
03 - Roast for 25 to 30 minutes, stirring halfway through, until sweet potatoes are golden and tender.
04 - While vegetables roast, rinse quinoa thoroughly 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 or until water is absorbed. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
05 - Whisk together tahini, lemon juice, olive oil, minced garlic, maple syrup or honey, and salt and pepper in a small bowl. Add 2 to 3 tablespoons water as needed for a smooth, pourable consistency.
06 - In a large bowl, combine cooked quinoa, roasted sweet potatoes and onions, baby spinach, and chopped parsley. Drizzle with dressing and toss gently to coat evenly.
07 - Serve the salad warm, garnished with pomegranate seeds if desired.
