A topping for specialty sandwiches and burgers is a flavorful, often tangy or savory condiment or relish designed to enhance the core protein and bread. Common examples include caramelized onions, sautéed mushrooms, bacon jam, or specialty pickles, and they are a staple in American diner and barbecue cuisine.
Nutrition varies widely by type, but many toppings are high in fat (like bacon jam) or carbohydrates (like sweet relishes) and add significant sodium. A typical serving adds about 50-100 calories to a dish.
