01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Toss sweet potato cubes with 1 tablespoon olive oil, 1/4 teaspoon sea salt, and black pepper. Spread in a single layer on the baking sheet. Roast for 25-30 minutes, turning halfway, until golden and tender.
03 - Combine quinoa, water, and 1/4 teaspoon salt in a medium saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
04 - While sweet potatoes and quinoa are cooking, massage kale with 1 tablespoon olive oil and a pinch of salt in a large bowl for 1-2 minutes until tender and bright green.
05 - Whisk tahini, maple syrup, lemon juice, olive oil, garlic powder, and sea salt in a bowl. Add water 1 tablespoon at a time until smooth and pourable.
06 - Divide quinoa among 4 bowls. Top with kale, roasted sweet potatoes, pumpkin seeds, cranberries, and feta if using. Drizzle generously with maple tahini dressing.
07 - Serve immediately, or refrigerate components separately for meal prep.
