This is the tuna salad sandwich from neighborhood favorite, Larchmont Wine & Cheese shop. It comes with tuna, mixed greens, balsamic, tomato, and emmenthal cheese. (Seen here minus cheese.)
The awesome and retarded thing about the Larchmont Wine & Cheese tuna sandwich is that, of the 7 available sandwiches on the menu, they don't number this one because it is only available occasionally. You have to call ahead to check. I have not been able to conceive of any reason the ingredients in this sandwich would not be available to a sandwich shop every day of the week.
I also heard a story about someone going to Larchmont Wine & Cheese, and the people there said they couldn't make any sandwiches that day because they were out of bread. I like you, Larchmont Wine & Cheese, but sometimes you are an asshole.
This is a pretty good sandwich.
