For an interesting twist to a Caprese salad (or a bastardization depending on who you ask) I like to use the following:

Tomatoes, Fresh Mozzarella, Basil, Avocado, Garlic, Olive Oil, Balsamic Glaze, Salt, Pepper.

Layer the tomato, avocado, mozzarella and basil leaves the way you would normally for a Caprese. Press one small clove of garlic (you can even use 1/2) in a garlic press and mix it with the olive oil, salt, and pepper as your dressing. To complete the salad, drizzle some balsamic glaze across the top.

It makes for a nice presentation and a very tasty, refreshing summer salad! I like to serve mine right away, but if you want to make it before a party or dinner, toss the avocado with a bit of lemon before hand so it doesn't oxidize, or add that right before serving.

I have to say, that watermelon gazpacho sounds very different and interesting (in a good way). I might have to make it on a hot day.
