Place chicken, bell peppers, tomato, carrot, and half of garlic into the slow cooker. Add enough chicken broth to cover, then add bay leaves. Cook on high for 4 hours or on low for 6-8 hours until chicken is tender.
Remove chicken and shred with two forks; set aside. Discard vegetables and reserve the broth.
Heat olive oil in a large skillet over medium heat. Add remaining garlic, onion slices, green peppers, and red peppers. Cook for 3-4 minutes until softened.
Stir in tomato paste and wine, cook 2-3 minutes. Add shredded chicken, tomato sauce, and about 3/4 cup of reserved broth. Season with cumin, garlic powder, salt, and pepper.
Simmer covered on low for 8-10 minutes, adding more broth and seasoning if needed. Garnish with chopped cilantro before serving.
