There are few things more frustrating than taking the time to build a delicious sandwich only to have all the ingredients slide out at your first bite. Although slippery sandwich fillings might seem like an unavoidable nuisance, there is a solution, and it’s surprisingly simple.

To avoid a slippery sandwich, it’s important to pay attention to the order in which you assemble your ingredients. Wet or slick ingredients like tomatoes and cucumbers should be separated from one another by something rough or dry like cheese or shredded lettuce.

Textured ingredients are the crux of a sturdy sandwich as they’ll hold everything together with friction. Once you’ve mastered alternating your layers, you can improve your sandwich game by keeping spreads away from bread, using the right type of bread, and putting any seasonings in the middle.
