Place each mozzarella round on a clean serving platter, spacing them evenly.
Gently top each mozzarella with a basil leaf, pressing down slightly to create an iris that sits flat on the cheese.
Insert a cherry tomato onto the center of each basil leaf, pressing slightly to resemble a blood-red pupil.
Optional: secure each assembled 'eye' with a toothpick or small skewer for easier handling, then remove before serving if preferred.
Arrange the completed eyeball bites on the platter, adding any additional decoration for a spooky effect if desired.
Serve immediately to enjoy the fresh, soft mozzarella and juicy cherry tomatoes, perfect for a festive Halloween snack.
