Preheat the Oven: Set oven to 400°F (200°C).
Season the Pumpkin: Toss the pumpkin wedges with olive oil, cinnamon, cumin, paprika, salt, and maple syrup. Spread out on a lined baking sheet.
Roast: for 25–30 minutes, flipping once halfway through, until the pumpkin is golden, tender, and slightly caramelized at the edges.
Make the Tahini Sauce: In a small bowl, whisk tahini, lemon juice, garlic, salt, and water until smooth and pourable.
Assemble & Garnish: Place roasted pumpkin on a serving plate. Drizzle with tahini sauce, sprinkle with dukkah, pomegranate seeds, chopped herbs, and chili flakes if using.
