Clean and chop the tomatoes and peaches. Roughly chop the cilantro and set aside.

In a medium-sized mixing bowl, combine the tomatoes and peaches. Pour the balsamic vinegar and olive oil over the fruit, sprinkle everything with salt, and top with the chopped cilantro.

Toss the salad to evenly combine, and place in a sealed container for transporting. If desired, you may bring some extra dressing and cilantro to top the salad when you reach your destination.
