Burger Sauce: Mix mayonnaise, tomato sauce, chilli sauce according to your taste.
Toasting Buns: Cut open the burger buns into half and toast on the inner side with a little butter.
Tikki With Cheese: To the same hot pan, add a splash of water, place tikki and place a cheese slice over the tikki, cover with the lid and leave it for 30 seconds to a minute or till cheese melts slightly. The steam in the pan helps to melt & soften the cheese slightly. Meanwhile quickly assemble the bun.
Assembling: Now, spread burger sauce on the inside of the toasted buns. Place a few lettuce leaves, tikki with the melted cheese slice, 2 slices of tomato, and a few onion rings on the bottom bun.
Cover with top bun and press lightly.
Enjoy the burger with fries and sauce of your preference!!
