Spread butter mixture onto the rolls. Cover both sides, edge to edge.
Layer on cheese, ham, and more cheese.
Place tops of the rolls back on. Bake at 350F until hot.
To be sure the cheese melts & the buns get crisp, microwave sliders for a few seconds before baking.
If you like yours soft, skip baking & microwave until hot.
