Assemble - Holding a skewer in your hand, pierce a cherry tomato, sliding it all the way to the end. Repeat that process with a piece of fresh basil, mozzarella ball, another piece of fresh basil and another cherry tomato.
Repeat - Repeat this process until you have used up all the ingredients.
Drizzle - Drizzle with balsamic glaze and serve.
Notes
Make Ahead: These are a great appetizer to make-ahead! Just assemble, store in an airtight container in the refrigerator and then drizzle with balsamic glaze right before serving.
