Have you been offered Hindu meals on flights? What is it? North Indian food, or South Indian? Does it include Dalit food? What is Dalit food?

The word "Dalit" homogenises hundreds of communities that are listed as Scheduled Castes and Scheduled Tribes. Some North Eastern restaurants do try to give us a taste of food eaten by North Eastern tribes, but as far as "lower caste" food is concerned, most Hindus have no clue about them.
