Slice the tomatoes and mozzarella. Alternate slices on a nice, big plate, overlapping each one slightly. You can add big leaves of basil in there as well. Sprinkle with salt. Let it sit for a bit with just the salt on there, if possible, to let things get juicy. With your hands, tear up a few leaves of basil and spread across the top. Drizzle olive oil and balsamic on top.
