Khalsa Tikki is a popular Indian snack made from spiced potatoes, often mixed with peas and various seasonings, shaped into patties and deep-fried until crispy. It’s commonly served with chutneys. Fast food, on the other hand, refers to quickly prepared meals, often associated with convenience and speed, including items like burgers, fries, and pizzas. Both offer delicious options for a quick bite, but Khalsa Tikki has a distinct cultural flavor.
