A ‌Cheese-&-Sausage-Bun‌ is a type of sandwich or burger bun that typically contains both cheese and sausage as key ingredients. It is often used in fast-food sandwiches or burgers, similar to how a ‌bun‌ (a small, round, flat-topped bread) is commonly used in hamburgers‌. The combination of cheese and sausage makes it a flavorful and hearty choice for a quick meal.
