This is easy, delicious, colorful, delicious, uses currently-in-season fresh corn and tomatoes, and, oh yes, is really good. I made a double batch of this yesterday for two of us, and we just polished off the rest of it this evening. BTW, Ordinary tomato is fine instead of plum tomato (and we happen to use more of it); I highly recommend flat-leaf parsley, if you can find it, because the curly stuff is not nearly as flavorful; You can use radicchio or any other kind of lettuce (if you choose to use any at all); The salad tastes even better the second day!; Flavor is better when served closer to room temp as opposed to ice cold.
