The Scooby Snack consists of a hamburger, a sliced sausage, a bacon rasher, a potato scone, a fried egg and a slice of processed cheese, all contained within a floured hamburger bun and accompanied by tomato ketchup and brown sauce. Fried onions are also offered as an optional extra. 
The Scooby Snack, because of the sausage, cheese, bacon and egg, takes similar resemblance to a breakfast roll but is often eaten at lunchtime.
The Scooby Snack's invention is commonly accredited to The Maggie, a food truck located at the intersection of Byres Road and Great Western Road. It is now sold by a number of after-hours fast food vendors throughout Glasgow.
A derivative, the Super Scooby, was invented by The Jolly Fryer café in Bristol in 2009. It consists of four quarter-pound beef patties, eight rashers of bacon, eight slices of cheese, 12 onion rings and six slices of tomato in a sesame seed bun, accompanied by salad, lettuce, barbecue sauce and mayonnaise.
Standing eight inches tall, the sandwich contains 2,645 kilocalories (11,070 kJ), which is more than the recommended daily intake of an adult male. The sandwich costs GB£10 and comes with chips; If both the burger and chips are consumed in one sitting, customers are given a free Diet Coke to aid digestion.
