Prepare a medium bowl and place inside: diced lamb, salt, turmeric, yogurt and ground coriander. Mix it all well and place, covered, in the fridge for an hour.
Using a blender, blend chilli pepper and the chopped leek.
After 1 hour of marinating the meat in yogurt ans spices, place removable slow cooker's pot on a medium heat. Spray it with oil spray. Add ground cloves, bay leaf, cumin, cardamom and fry gently and quickly.
Add the marinated meat into the pot with fried spices and mixing, fry for 3-5 minutes, until the meat browns.
Add the chilli and leek blend and a Low FODMAP chicken stock into the pot. Mix well and bring it to boil. Remove the pot from the heat and place it in the slow cooker's base. Cook on high setting for at least 6 hours. In the middle of cooking add the vegetables: green beans and fresh spinach.
Slow cookers vary, therefore always before serving check that the meat is cooked through and is soft.
