In a mixing bowl, combine the extra-virgin olive oil, chopped sun-dried tomatoes, chopped kalamata olives, minced garlic, garlic powder, crushed red pepper flakes, onion powder, dried basil, and dried oregano. Mix well to ensure all ingredients are evenly distributed.
Stir in the chopped fresh chives and parsley to add color and flavor to the marinade.
If using block mozzarella, cut it into bite-sized cubes. If using mozzarella balls, leave them whole.
Gently add the mozzarella to the marinade, ensuring each piece is well-coated. Transfer the mixture to a glass jar or container with a lid.
Seal the jar or container and refrigerate for at least 2 hours, preferably overnight, to allow the flavors to meld beautifully.
