Combine the allspice and 3 teaspoons salt in a small bowl. Season the turkey thighs with half the salt mixture in a 5-quart slow cooker.
Toss the squash, chickpeas, tomatoes, apricots, raisins, carrots, onions and chiles with the remaining spiced salt. Pour the vegetables over the turkey (the cooker will be full; arrange the mixture so the lid fits). Cover and cook on high for 6 hours or on low for 7 to 8 hours.
Spoon the vegetables and broth into bowls. Remove and discard the turkey bones and place the meat on top of the vegetables.
Juice the lemon; pulse with the cilantro, parsley, garlic, cumin and 1 teaspoon salt in a food processor. Add the oil and process until smooth. Serve the stew in bowls; drizzle with the cilantro sauce.
Leftovers from this dish can be used to make Moroccan Burritos.
