In a skillet over medium heat, add onion, garlic, and oil. Saute for 2-3 minutes. Add the ground chicken and seasonings. Saute for 8-10 minutes.
Add the seasoned ground chicken, and remaining ingredients into a 6-quart or larger sized slow cooker and stir to combine. Cover and cook on low for 4 to 6 hours or high for 3 to 4 hours.
Once the chili is finished, serve into bowls and top with a squeeze of fresh lime juice and then add any of your favorite toppings! Enjoy!
