Peel and thinly slice onions, then fry in oil until slightly golden. Wash and cut meat into small pieces and fry in onions until color changes. Add 3 glasses of hot water and bring to boil. Turn heat down and let boil slowly for about 45 minutes, adding more hot during cooking water if needed.
While meat is cooking, wash French beans, cut the ends and chop into 2-3 cm pieces. Add French beans, salt, pepper and tomato paste to the meat and continue until cooked. Add lime juice and adjust seasoning. Cook for another 3-4 minutes. Khoresht Loobia-Sabz should be served with white rice.
If desired, potatoes can also be added to Khoresht Loobia-Sabz. In that case, wash, peel and cut 500 grams of potatoes into small pieces and add in with 500 grams of French beans (note that required cooking time depends somewhat on the size of the cut pieces).
