A vegetarian friend of mine invited me to his birthday dinner in a few days. He's an awesome guy and deserves the best he can get (he also has solid culinary training, although that wouldn't affect my mission either way). The dinner is a tomato themed potluck. I prefer good tomatoes solo, raw, unembellished, but I know that I can't show up that way. I imagine the usual suspects (salads, especially caprese, gazpacho, sauces on pasta, etc) will be covered. Any recommendations for new territory? I have a couple sources for good dark princes, striped germans and brandywines that I can hit up the day before.
