Combine the onion, garlic, carrots, chickpeas, tomatoes, 1 tablespoon lemon juice, chicken stock, salt, cumin, cinnamon, and chicken in a 6-quart slow cooker.
Cover and cook on high for 4-6 hours or low for 6-8 hours, or until the chicken is tender.
Remove the chicken from the slow cooker and shred with two forks. Add the shredded chicken, along with 1 tablespoon lemon juice, the spinach, and the chopped apricots back to the slow cooker, stirring to combine. Taste and add additional salt and lemon juice to taste. Let sit 5 minutes to allow the spinach to wilt and the apricots to soften.
Serve hot, with rice, crusty bread, or on its own. Top with green onion, cilantro, and hot sauce, if desired.
