Melting

Melting butter with cheese allows for a rich, creamy texture that enhances the flavor. Combine with mustard for a tangy addition.

Toasting

Toasting bread adds a crunchy texture and a warm base for your sandwich. Ensure each slice is evenly toasted for the best outcome.

Layering

Layering the ingredients thoughtfully in the sandwich ensures that each bite has a balance of flavors and textures, with the beef and onions complementing the melted cheese.
