Slice tomato and mozzarella into five equal pieces. Arrange tomato and mozzarella slices on a platter. Add basil leaves between the slices. Drizzle pistachio oil over the top of the salad, getting a little bit on each slice. Do the same with the balsamic vinegar. Finish with toasted and chopped pistachios and a sprinkling of kosher salt and freshly ground black pepper. 

Pro Tip:

Pistachio oil is a pressed oil, extracted from the fruit of Pistacia vera, the pistachio nut. Pistachio oil has a particularly strong flavor and tastes like the nut from which it is extracted. Pistachio oil is high in Vitamin E and is used as a table oil to add flavor to foods such as this amazing Caprese Salad.
