Pre-heat your oven to 375˚.
Slice the Hawaiian rolls in half and place the bottoms into your baking pan.
Layer ham on top of rolls, then Swiss cheese, pickles and then close with top buns.
In a small bowl, mix together the butter, dijon and the dried minced onions. Pour mixture over the top of the closed sliders.
Top sliders with foil and place in the oven for 15 minutes, remove foil and cook for another 10 minutes, until the rolls are getting browned.
