01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper and set aside.
02 - In a mixing bowl, toss the sweet potato cubes with olive oil, smoked paprika, ground cumin, sea salt, and black pepper until evenly coated. Spread the cubes in a single layer on the prepared baking sheet. Roast for 25 to 30 minutes, flipping halfway through, until golden and fork-tender.
03 - While the sweet potatoes roast, combine the rinsed quinoa, water, and sea salt in a medium saucepan. Bring to a boil over medium-high heat, then reduce the heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
04 - In a small bowl, whisk together the tahini, fresh orange juice, lemon juice, maple syrup, minced garlic, and sea salt until smooth. Gradually add water, one tablespoon at a time, until the dressing reaches a pourable consistency.
05 - Divide the fluffed quinoa and mixed greens evenly among four serving bowls. Arrange the roasted sweet potatoes, pomegranate seeds, toasted pumpkin seeds, chopped cilantro or parsley, and sliced red onion over each bowl.
06 - Drizzle the citrus tahini dressing generously over each bowl just before serving. Serve immediately.
