Mix all the ingredients except the chicken breasts together in a bowl.
Oil the slow cooker pot lightly to prevent sticking.
Place three chicken breasts in the pot and the other ingredients on top, mix to cover.
Cook on high for 3-4 hrs or low for 5-6.
Notes
SidesServe with a squeeze of fresh lime juice and chopped fresh coriander. Delicious with coconut rice (for a quick version of this, use a tin of coconut milk, plus a little water, to cook your rice).
