Prepare the dressing by mixing vinegar, mixing sugar, Parmesan, oil, Italian seasoning, garlic powder, and salt.
Heat salami in a non-stick skillet over medium heat until it browns, then drain on paper towels.
Distribute lettuce, black olives, tomatoes, blue cheese, mushrooms, and the cooked salami across four salad dishes.
Finish by adding the dressing to each salad before serving.
