Make the Dressing: In a small bowl, whisk together vegetable oil, lemon juice, garlic, salt, pepper, Parmesan cheese, and (optional) sugar. Cover and refrigerate for at least 24 hours.
Assemble the Salad: In a large bowl, combine the chopped romaine lettuce and chilled dressing. Toss to coat evenly.
Add the Toppings: Sprinkle the salad with crumbled bacon, black olives, toasted almonds, diced tomato, and shredded mozzarella cheese.
Serve and Enjoy! Toss everything together again and serve immediately.
