Need:
Heirloom tomatoes of your favorite sort
Good sturdy sandwich bread ( i like multi-grain but white's all good)
Mayo (not miracle whip. i assume i don't even have to say that here.)
Nice flaky salt
Pepper
Do:
Toast bread. While it's still very warm (you should move it right from the toaster to this step) spread with mayo on one side. Don't go nuts, but don't be mean about it either. Top with 1-2 thick slices of tomato, salt liberally, pepper it up and enjoy open-faced. Make a few, you're gonna want them. Add some fresh basil leaves if you're the sort to mess with perfection.
