Slice chicken breasts into bite size pieces, about 1 inch chunks.
Lightly grease the inside of your crock pot or slow cooker with olive oil.
Add chicken, tomatoes, minced garlic, minced ginger, garam masala, cumin, paprika, onion powder, salt, tumeri, black pepper, basil, cinnamon, and cayenne pepper into the slow cooker. Stir to combine.
Cook on low for 8 hours or high for 4 hours (I did the latter).
After the timer finishes, add cream and cornstarch to the slow cooker, stir, and cook for an additional 30 minutes.
Add lime juice and stir. Serve over rice or riced cauliflower.
