Tomato sandwich, it sounds simple but it kicks fucking ass. This sandwich lives or dies on having good flavorful tomatoes so its only for in-season times of year.
You want to make it with plain white sandwich bread - toast it lightly. Apply a light layer of real (not miracle whip) mayonnaise - preferably full fat. Then slice a beefsteak tomato into slices that let you retain all the guts of the tomato but are otherwise relatively thin. Make sure to cut out the stem joint (I usually do this after slicing because it's easier). Assemble your sandwich with a reasonable amount of tomato but as you put slices on salt your tomato. A modest size tomato is usually large enough to make 2-3 sandwiches.
Enjoy a fucking treat!
