Ingredients

• 2 (15-ounce) cans chickpeas, drained, rinsed, patted dry
• 8 ounces button mushrooms, quartered (about 3 1/2 cups)
• 2 teaspoons curry powder
• 1/2 teaspoon ground cumin
• 5 tablespoons olive oil, divided
• 1 1/2 teaspoons kosher salt, divided
• 4 medium sweet potatoes (about 9 ounces each)
• 5 ounces baby spinach (about 4 packed cups)
• 2 limes
• 1/2 cup Greek-style plain full- or low-fat yogurt
• 1/2 cup coarsely chopped cilantro, plus whole leaves for serving

Instructions

1. Preheat oven to 450°F. Toss chickpeas, mushrooms, curry powder, cumin, 2 Tbsp. oil, and 3/4 tsp. salt on a rimmed baking sheet. Divide mushrooms and chickpeas into separate piles and spread in a single layer.
2. Cut potatoes in half lengthwise. Rub with 1 Tbsp. oil and 1/2 tsp. salt and transfer cut side down to another rimmed baking sheet.
3. Roast vegetables and potatoes, rotating pans halfway through and arranging spinach over vegetables during the last 2 minutes of cooking, until chickpeas are golden brown and crisp and potatoes are fork-tender, about 25 minutes.
4. Meanwhile, juice limes to yield 6 Tbsp. juice. Blend yogurt, 4 Tbsp. lime juice, and 1/2 cup chopped cilantro in a blender until smooth.
5. Transfer spinach, mushrooms, and chickpeas to separate bowls. Transfer potatoes to a serving platter. Using the back of a spoon, gently push down in center of potato halves to create a divot.
6. Spoon vegetables into divots, then top with yogurt sauce and cilantro leaves.
7. Potatoes, chickpeas, and mushrooms can be cooked 3 days ahead; store separately, cover, and chill. Reheat in oven before serving.
