To Make in the Slow Cooker / Crock Pot: Make the marinade and marinate the lamb per the recipe above. Cook the onions and peppers in a hot pan per above, then transfer to your slow cooker with 1 cup stock. Slow cook in high for 3-4 hours, or on low for 6-8 hours, until the lamb is tender. If it becomes too dry, add a bit more stock. Stir in the heavy cream or coconut milk during the last 10 minutes to warm through.
