Preheat the oven to 425°F (220°C).
In a large bowl, toss the butternut squash with olive oil, cumin, smoked paprika, salt, and pepper until well coated.
Spread the seasoned butternut squash in a single layer on a baking sheet and roast for 25-30 minutes, or until tender and slightly caramelized, stirring halfway through.
While the squash is roasting, prepare the chickpeas by patting them dry with paper towels. In a separate bowl, toss the chickpeas with a drizzle of olive oil and a pinch of salt.
Spread the chickpeas on a baking sheet and roast in the oven with the squash for the last 15-20 minutes, until crispy and golden.
For the tahini dressing, whisk together tahini, lemon juice, minced garlic, and warm water in a small bowl until smooth. Add salt to taste and adjust consistency with more water if needed.
Once the squash and chickpeas are done, remove from the oven and let cool slightly.
Arrange the roasted squash and chickpeas on a serving platter. Drizzle with the tahini dressing and garnish with chopped parsley and pomegranate seeds, if desired.
Serve immediately and enjoy the flavors of the Mediterranean!
