How many calories in a sausage butty?

A sausage butty, which typically consists of a sausage in a bread roll, can range from about 400 to 700 calories, depending on the type of sausage and the size of the roll. A standard pork sausage adds around 200-300 calories, while the bread roll contributes another 150-300 calories. Additional toppings, such as sauces, can further increase the calorie count. For a more accurate estimate, it's best to check specific ingredients used.
