Place all ingredients except coconut milk and spinach in the slow cooker and stir to combine.
Cook in slow cooker on high for 4 hours.
Remove chicken and shred, then return to the pot.
Add coconut milk and spinach, and let sit for another 10 minutes or so, until spinach is wilted.
Serve over rice with a slice of lime juice and cilantro
Notes
*Thai curry paste can vary in intensity. Use caution, and start small, especially if you don’t want much heat. I like to add all the ingredients to the slow cooker except for chicken, then taste test and add more if needed.
