Tomato sandwiches are a staple food in the American south. Tom Robbins even developed a rich a storied recipe for them in at least one of his books. He specifies Wonder Bread. I personally like them this way:

(Makes 2)

1 large, sun-ripened, slightly squishy tomato, which has never been cooled below 50 degrees F, sliced

4 slices of white sandwich bread

A generous amount of mayonnaise, I prefer Duke's, when I can get it

fresh ground black pepper

--

Slather the bread with the mayo, grind on some pepper, slap on the tomato and eat. Maybe with a bunch of napkins. Maybe over the sink. It really depends on the squish level of the tomato.
