Step 1

Heat the oven to 400 degrees. On a large rimmed baking sheet, toss the squash and thyme with 2 tablespoons oil; season with salt and pepper. Spread in an even layer. Roast until the squash is tender and just beginning to turn golden-brown, 35 to 40 minutes.

Step 2

As squash roasts, toss the onion, vinegar, garlic, turmeric and ginger in a large bowl; let marinate at least 10 minutes. Add the chickpeas and the remaining 1/4 cup oil and stir to coat. Toss in half the herbs and season with salt and pepper.

Step 3

Divide the salad greens among 4 bowls and top with the roasted squash. Serve with a generous amount of the marinated chickpeas, and a dollop of yogurt. Garnish with the pomegranate seeds, if using, and the remaining torn herbs.
