Chef van Nostrand
OP, it sounds like youve only had the snack food/americanized version of these cuisines.
Also, a lot of other cultural foods have a very similar offering of starchy wrap, savory filling and sauce in their snack foods, some of which are americanized, some more or less authentic. Some examples:
- chinese potstickers, egg rolls, sticky buns
- english pot pies
- jewish Knish
- central european pirogis
- italian calzone
- french crepes and various sandwiches
With the exception of cultures in the arctic, all cultures have developed some sort of food that can be described in general terms the way you did. If you think all indian food fits into that one category you described, you havent had 90% of indian food, which is diverse as you should expect from a country of a billion people spanning a huge range of climate and geography.
A billion people and no Michelin stars.
