Well, here are some very popular (and delicious!) Indian junk food -
Paav Bhaji
roughly translated - Paav means "bread", and "bhaji" is the curry, usually potato and peas based.
To make "bhaji", potatoes are mashed on a flat pan called a tava, and made into a thick gravy after adding diced tomatoes, finely grilled onions, green peas, capsicums (green pepper) and other vegetables like cauliflower and carrots. A special blend of spices simply called the "pav bhaji masala" is added to this thick gravy. The gravy is then allowed to simmer on the pan for a few minutes and is served hot in a flat dish with a tablespoon of butter on top.
The "pav" (bread) is roasted on the same pan with an ample amount of butter and a "masala" (usually chilli powder and salt). The Bhaji is garnished with diced onions and a slice of lemon and served with the pav.
In restaurants some more varieties are available including Cheese Pav Bhaji with added cheese on top, "Paneer" Pav Bhaji with added paneer (cottage cheese), Mushroom Pav Bhaji, "Khada" Pav Bhaji (vegetables not mashed, but small pieces cooked with masala gravy), and Dryfruit Pav Bhaji with added dryfruits.
