Season the mozzarella pearls with oregano, salt, and pepper.
Add olive oil, mix, and let marinate for 30 minutes (or overnight in the fridge for a more intense flavor).
To assemble: place a cherry tomato on a mini skewer, fold a basil leaf, add a marinated mozzarella ball, then another cherry tomato, basil, and mozzarella.
Arrange the appetizers on a serving platter, drizzle with balsamic cream, and enjoy. Bon appétit!
