Prepare Ingredients: Drain olives if they’re stored in brine, and pat dry. Cut cheese into bite-sized cubes (¾-inch pieces work best).
Mix Marinade: In a large mixing bowl, whisk together olive oil, red wine vinegar, sliced garlic, herbs, pepper flakes, lemon zest, and salt.
Add Olives and Cheese: Add the olives and cheese cubes to the marinade, gently stirring to ensure everything is well coated.
Marinate: Transfer the mixture to a glass jar or airtight container. Seal tightly and refrigerate for at least 2 hours, preferably overnight.
Serve: Before serving, allow the mixture to come to room temperature for about 20–30 minutes. Stir gently, and drizzle with extra olive oil if needed.
