Starting out, preheat oven to 350°F.
Open your pack of buns and cut them in half, setting the top half to the side, cover the tops of the bottom half with mayo or butter.
Toast in the oven 3-5 minutes, carefully remove and add provolone cheese, half of mixture to each set of 12 sliders and place the top buns on.
Next, brush on the melted butter and sprinkle on ranch and parsley.
Bake an additional 3-5 minutes or until desired color appears.
