Cauliflower-and-Chickpea Pitas with Creamy Yogurt Sauce

Preheat oven to 425°F. Arrange cauliflower and chickpeas on a rimmed baking sheet. Sprinkle with cumin, season with salt and pepper, and toss with oil. Roast, flipping vegetables once, until golden and crisp, 30 to 35 minutes.

Meanwhile, combine garlic, cilantro, jalapeño, lime juice, and yogurt in a blender. Blend until smooth. Season with salt and pepper; if too thick, blend in 1 tablespoon water. Heat pitas in oven until warm, 1 minute. Split pitas and stuff with cauliflower mixture; drizzle with yogurt sauce, garnish with more cilantro leaves, and serve.
