What key ingredients are on the smash burger sliders?

The smash burger sliders are characterized by their combination of American cheese, diced onions, pickles, and a secret sauce served on King's Hawaiian bread. This combination is essential because it captures the classic flavor profile of a smash burger, which typically emphasizes the savory taste from the beef patty and the richness of the melted American cheese. The diced onions add a layer of flavor and crunch, while the pickles contribute a tangy contrast that enhances the overall taste experience. The secret sauce functions like a special condiment, often combining elements of mayonnaise, ketchup, and other seasonings to create a unique flavor. The use of King's Hawaiian bread provides a slight sweetness and a soft texture that complements the savory ingredients, making it a popular choice for sliders.
