Heat a large pot over medium heat with olive oil. Add onions and garlic and sauté for 3 minutes.
Add cauliflower, red peppers, chicken, seasonings, and broth. Add more broth as needed until everything is fully covered. Bring to a simmer; cover with a lid and simmer for 10 - 15 minutes, or until chicken is cooked through to 165°F (74°C).
Remove chicken and shred with forks.
Return chicken to pot along with spinach, feta, cream cheese, and lemon juice. Simmer for 5 - 10 more minutes to allow liquid to thicken a bit.
Portion into bowls. Serve and enjoy with naan and glasses of cold apple juice.
