If you are using dried peas, then soak in water for 6 hrs min and cook to get soft ones. Carrot, potatoes can be boiled along with peas.
Mix corn flour in water to get a dropping consistency. Get bread crumbs ready.
Mix all the ingredients for patties. Roll them as long patties and dip in corn flour, then in bread crumbs.
This can be either deep fried or shallow fried. I did a shallow fry as its better tasting.
Heat cooking oil in a pan and place the long patties and add 1 tbsp to fry each patties.
Once all the patties are ready, make a long slit on one side of the bun making sure its still intact.
Apply sauce, grated cheese, then place the patties inside. Sprinkle generous amount of cheese if you like cheese on top of the patties.
Bake it in oven or microwave until the cheese melts. Finally you can sprinkle pepper and sauce over the top before serving.
