After 20 minutes of roasting, in a medium bowl, combine chickpeas, red onion, remaining ¾ teaspoon baharat, ¾ teaspoon salt and 1 tablespoon oil, and toss until well combined. Add the mixture to the pan of squash and stir everything well. Continue roasting for another 30 minutes, tossing the mixture halfway through, until the squash is golden brown and tender, and the chickpeas and onions are slightly crispy.
