There is no set type of bun that works best with these Mississippi sin ham sliders. While they are called sliders, you can make them with a traditional sandwich bun size if you prefer. Some common options are Hawaiian rolls, dinner rolls, sesame seed buns, poppyseed buns, onion rolls, or even pretzel rolls. For a little sweeter and more buttery option, you can make these with brioche buns or even croissants.
