One pan cook lamb shoulder and veg

Season lamb with salt, black pepper and lots of cumin grain for a few hours. At medium heat, sear fat side down first, with bell pepper cut into strips around. When pepper starts to soften, add stalks of Kallan to cook in the rendered lamb fat. 

Turn lamb over and add Kailan leaves, cover with lid. When Kailan cooked, remove from pan, and continue cooking lamb until ready, I like pink in the middle.
