I first wash the greens and tomatoes. That is very important especially because you aren't cooking it. I then slice the tomato and slice the mozzarella. I put one mozeralla slice per tomato slice, then add a basil leaf on top. I lightly drizzle the olive oil and then garnish with a sprinkle of salt and freshly ground black pepper. A few other alternatives is adding balsamic vinegar or a reduction to it to make it more sweet. Also, if you are on the go- using grape tomatoes, mozzarella balls, and basil and using the olive oil as a dressing makes a nice salad!
