Cook the lentils in the stock with the onion and garlic until the lentils are soft.
In a food processesor put the lentils and the rest of the ingredients (other than the oil).
Allow the mixture to cool.
Heat a pan to medium high heat and put in the oil.
Using a bowl of water to keep your hands wet make little balls and fry them in the oil (alternatively, pop them into mini muffin tins and brush with oil. Bake till golden)
