Divide the pitas in half so you have 24 half-moon pockets.
Stuff each pocket with 3 to 4 pieces of mozzarella and set aside.
Place the tomatoes in a small bowl and drizzle with the olive oil. Add the salt and toss to combine.
Add some tomatoes to each pita pocket, and finish with a little basil and ground pepper. Serve immediately.
Trader Joe's mini pitas work especially well. They're tasty and are the smallest we have found.
