Preheat oven to 350 degrees.
In a sauce pan over medium heat whisk together all of the sauce ingredients. Bring to a simmer, add meatballs, and cook for about 10 minutes until meatballs are heated through.
While the meatballs and sauce are heating, add the packaged salt to the pretzel rolls as directed on the packaging. Slice the pretzel rolls and place onto a baking sheet. Heat in the preheated oven for about 3-5 minutes, just until heated through or lightly toasted.
To assemble sliders, add 2 meatballs to each bottom bun, top with prepared coleslaw, and top with bun. Enjoy immediately!
I used mini pretzel rolls for these and they worked great, and were delish! Any slider bun would work though like Hawaiian buns, yum!
You may need to adjust your number of meatballs depending on what size they are, and what size your buns are. The sauce makes plenty and would go further than 12 meatballs if you decide to make more. Leftover sauce could be saved, refrigerated, and used for up to a week.
