An onion sandwich is a staple of the South and exactly what it sounds like: Slices of onions flanked by bread, smeared with a layer of butter or mayo.

A Southern onion sandwich starts with raw Vidalia onions grown in Georgia. For this sandwich, you will want to slice the onion into circular pieces.

Add salt and pepper to enhance the flavor, then spread mayo on your favorite bread. Once you assemble the sandwich, you want to roll the edges in finely chopped parsley.
