First, prepare chaat sauce by combining all ingredients in a blender and blending until smooth and creamy.
Remove hot dogs from package into a shallow dish and poke holes with a fork all over hot dogs.
Pour half of chaat sauce all over hot dogs in shallow dish, and marinate in fridge for at least 4 hours. Reserve other half of chaat sauce for topping hot dogs.
Once hot dogs are finished marinating, heat a non-stick pan or a grill pan and cook hot dogs as package indicates (e.g., each hot dog should cook in just a few minutes on each side until browned). Set hot dogs aside on a dish when finished.
Butter hot dog buns and toast or grill on a pan.
Assemble hot dogs by placing hot dog in bun, and garnishing with suggested garnishes of your choosing (e.g., chutneys, chopped onions, tomatoes and cilantro, chaat sauce, chaat masala and red chili powder).
Serve immediately and enjoy!
