you can put some lettuce leaves and mayonnaise to the burger bun….

to the bun, slit it into half, then spread mayonnaise, and then put the lettuce leaves, and then put the onion and then the chiken tikki, then the tomato and then the top part. Put a tooth pick across, with a small cherry inserted….

Eat the burger with English mustard or mayonnaise or tomato sauce…..

and a small correction, it would be chicken burger, and not hamburger, because hamburger means it is made with beef, and comes from a place called Hamburg in Germany….
