To make patties, heat oil in a pan, add onions and sauté till it's translucent. Add all the veggies, mix well, cover and cook till they are done. Add salt, turmeric and chilli and saute for a minute or two. Add maida, mix and cook for another 3-4 minutes while mixing frequently.
Remove the veggie mixture from heat. Mash it with a potato masher while it's still hot. Divide the mixture into 4 portions. Make smooth balls. Pat them a bit to give it Patti's shape. Dip them in slurry and then roll in the bread crumbs one by one. Shallow fry them with 2 tbsp oil in a nonstick pan on the lowest flame.
Mix all the ingredients for mayonnaise spread. Keep aside.
For salad, boil potato chips in mildly salted water. Ensure that they do not break due to overcooking. Melt butter on a pan. Saute peppers for a minute or two. Sprinkle black pepper powder and salt. Add potato chips. Mix well and remove from heat. Add a tbsp and a half the mayonnaise spread and mix evenly. Keep aside.
Cut apart buns at the middle. Spread a little butter on both the inner sides of a bun. Lightly toast the buttered side without giving any pressure to the buns(We do not want flat buns). Apply mayonnaise spread on both sides of a bun. Put a lettuce leaf on the top, followed by a Patti.
Put a cheese slice on the top of the Patti. Top it up with the salad prepared earlier. Cover it with the other slice of the bun. Put a piece of red bell pepper or cherry tomato on the top of the bun and pass a toothpick through it piercing the bun too.
Type of mayonnaises to use : any mayonnaise that is not tangy will do. I like Veeba's burger mayonnaise, Nando's perinaise, Crosse and Blackwell Burger mayonnaise.
