Mix all the above ingredients in a bowl. The mixture should not be too soft, or else the patties wont retain their shape. To harden it, add some more gramflour.
Shape into ovals / rounds. Grease a non-stick pan with a tspn of oil, and place the patties. Cook till golden brown and crisp on the outside, on both sides.
This should take around 5-7 minutes per side on a slow flame.
Serve with chutney / tomato ketchup.
