01 - Preheat the oven to 425°F. Line two baking sheets with parchment paper.
02 - In a saucepan, combine the quinoa, water, and salt. Bring to a boil, reduce heat to low, cover, and simmer for 15 minutes (or according to package instructions). Fluff with a fork and set aside.
03 - Toss the zucchini and red onion with 2 tbsp olive oil, salt, and pepper. Spread on one baking sheet in a single layer. Roast for 20–25 minutes, flipping halfway, until golden and tender.
04 - Toss the chickpeas with 1 tbsp olive oil, smoked paprika, garlic powder, and salt. Spread on the second baking sheet and roast for 25–30 minutes, shaking the pan halfway, until crispy.
05 - In a small bowl, whisk together tahini, lemon juice, olive oil, maple syrup, salt, and 2 tbsp water. Add more water to reach a creamy, pourable consistency.
06 - Divide the cooked grains among four bowls. Top with roasted zucchini, red onion, crispy chickpeas, cherry tomatoes, cucumber, and fresh parsley. Drizzle generously with tahini lemon dressing. Sprinkle with toasted pumpkin seeds if desired.
07 - Serve immediately, with extra lemon wedges on the side.
