This is a very tough one. With a gun to my head I would probably land at:

-Italian
-American -- hard to pick a specific region but thinking: fresh caught fish and shrimp from the NC fish (low country boil type meal), NC BBQ, steak and mashed potatoes, burger and fries, shrimp and grits, crawfish, brown butter lobster, cornbread, stovetop mac and cheese, etc.
-Greek/Turkish

I find it hard to believe that I'm leaving off Indian (UK Indian -- give me the entire Dishoom menu), TexMex, and Japanese (sushi as a standalone would make this dish and I love a good ramen but it doesn't quite make it all the way to the top -- especially with the lack of authentic Japanese restaurants near me)
