30 ml (2 T) oil
Heat the oil in a heavy-based saucepan and brown the meat strips. Remove from the saucepan and set aside. Fry the onions, garlic and ginger in the remaining oil until tender and fragrant.
Return the meat to the saucepan and season with curry powder, turmeric, brown sugar, lemon juice, and salt and black pepper. Stir-fry for about 5 minutes. Add the water, reduce the heat and simmer for about 1 – 1 ½ hours or until the meat is nearly tender.
Add the sweet potato cubes and fresh green beans (if using) and simmer for another 25 minutes or until the sweet potatoes are tender. Add the canned green beans (if using) and simmer for another 5 minutes until warmed through. Serves 6 – 8.
Serve with rice
