In a pan, with a tsp of oil saute chopped onions, garlic and ginger. Fry them until they become transparent and soft. Mix these and all the other ingredients mentioned in this section, in the mince and prepare round patties.
Apply some oil on a frying pan and start frying the patties on medium heat. Keep the flame medium so the mince gets cooked from inside. Turn them and make them brown from both sides. In the end, place the slice of cheese on each patty and take them off the pan after two minutes.
Half each bun and toast them from the white side in the same pan as you fried the patty.
Spread the prepared sauce on both sides of the bun and place the patty and other fillings of your choice.
