01 - Preheat the oven to 400°F. Toss sweet potato, red bell pepper, and red onion with olive oil, salt, and black pepper. Spread evenly on a baking sheet lined with parchment paper. Roast for 20 to 25 minutes, tossing halfway through until vegetables are tender and lightly browned.
02 - Combine quinoa and water in a medium saucepan. Bring to a boil, reduce heat, cover, and simmer for 15 minutes. Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork.
03 - Whisk together tahini, lemon juice, maple syrup or honey, olive oil, salt, and 2 to 3 tablespoons of water in a small bowl until smooth and pourable.
04 - In a large bowl, combine cooked quinoa, roasted vegetables, chickpeas, pumpkin seeds, dried cranberries, and baby spinach. Drizzle with the dressing and toss gently to combine.
05 - Serve warm or at room temperature.
