01 - Preheat the oven to 425°F and line a baking sheet with parchment paper.

03 - Spread the vegetables evenly on the prepared baking sheet and roast for 25 to 30 minutes, stirring once halfway through, until golden and tender.
04 - While the vegetables roast, whisk together tahini, lemon juice, water, minced garlic, salt, and ground cumin until smooth. Add additional water if needed to achieve pourable consistency.
