Not Necessarily in White bread, Generally we refer to sausages as snags, and doesn't need to be in bread to be referred to as a Snag. some people prefer their snag in Grain bread or brown bread. Either way, it's a meal fit for a king, There's two variations on the placement of the snag on the bread, the most common being placed diagonally on the bread, Myself I prefer the the snag horizontal to the crust of the bread as this ensures a good bread to snag ratio upon the first bite.

We've recently had some controversy form over the famous snag in bread when a customer at an Australian hardware store that's sells the Famous "Bunno's Snag" had Slipped on an onion. after an investigation, the team came to the conclusion that the Onions must be placed on the bread prior to the Snag to prevent the onions from falling out of the meal and onto the ground, Thus preventing the risk of injury if a fellow patron were to slip on said onion.
