A sausage sizzle (also referred to as 'sausage in bread' or a sausage sandwich) is a grilled or barbecued food item and community event held in Australia and New Zealand. A sausage (most commonly beef or pork) is served in sliced bread or a hot dog bun with grilled onions and various condiments, most commonly tomato sauce, barbecue sauce or mustard.

Most commonly, the main sale item at a sausage sizzle is a pork or beef sausage (often referred colloquially in Australian slang as a 'snag'), cooked on a grill or barbecue and served on a single slice of white bread, or a hot dog roll in Western Australia.
