01 - Preheat oven to 425°F. Line a baking sheet with parchment paper for easy cleanup.
02 - Toss the butternut squash cubes with olive oil, salt, and pepper. Spread in an even layer on the prepared baking sheet. Roast for 25–30 minutes, flipping halfway through, until golden and tender.
03 - While squash roasts, combine quinoa, water, and 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 - Massage kale with olive oil and a pinch of salt in a large bowl until leaves become glossy and slightly softened, about 2–3 minutes.
05 - Whisk together tahini, lemon juice, maple syrup, water, sage, salt, and garlic until smooth. Add more water, 1 teaspoon at a time, if needed to achieve pourable consistency.
06 - Divide cooked quinoa between 4 bowls. Top with massaged kale, roasted butternut squash, and drizzle generously with sage tahini dressing. Sprinkle with toasted pumpkin seeds and crumbled feta cheese if desired. Serve immediately.
