Great and impressive looking appetizer. I use "Good Seasons" Italian dressing instead of the sugar, salt, pepper, onion, and garlic, it's easier and tastes better too. And I use fresh basil, instead of dried.
The best things in life are cheese. Marinated cheese recipes you need in your life: Herbed Goat Cheese Balls, Mozzarella Marinated in Herbs and Red Pepper Flakes, Spicy Marinated Feta, Italian-Marinated Colby Jack with Olives, Marinated Bocconcini (mini mozzarella balls with lemon, garlic and peppercorns), Marinated Greek Yogurt (yep, it's a thing!)
