I am only posting such a simple recipe because I actually somehow lived 29 years of life before my husband introduced me to the Tomato Sandwich. If you've only used tomatoes as an accessory in your sandwiches, and not as the Featured Ingredient, you are truly missing summer as it was meant to be tasted. Note: after many years, I have solidly converted to mayo for this sandwich, with fresh ground black pepper too. (Oct 2012)
