Combine all the ingredients and leave it marinate for at least 6 hours or preferably over night
When ready to eat fry them in oil on medium low heat, frying at a high heat will make the kababs hard, you want to cook the inside and char the outside a little.
Serve hot with chapati
Notes
For a kabab you can shape use ½ cup of papaya paste, but for a creamier more paste like kabab increase it to ¾ cup.
