Parmesan cheese (I used about 1/4 shredded and sprinkled on top of rolls)
Step 1: Preheat oven to 350. Cover 9×13 baking pan with foil. Spray with cooking spray.
Step 2: Remove rolls from package in one piece.
Step 3: Cut entire slab of rolls in half lengthwise. (You will end up with one slab of “tops” and one slab of “bottoms”.)
Step 4: Place bottom slab in foiled cover pan.
Step 5: Layer with half of the ham , then the Swiss cheese, then the rest of the ham.
Step 6: Add top slab of rolls.
Step 7: Melt butter in microwave and whisk in remaining ingredients (except parm. cheese and parsley). Pour evenly over rolls. Sprinkle with Parmesan and parsley. (The original recipe says to do that at the end. I liked it adding a little crispiness to the outside of the roll so I did it before I baked them.)
Step 8: Cover with foil and let sit for 5-10 minutes.
Step 9: Bake covered for 20 minutes.
Step 10: Uncover and cook 5 additional minutes.
Step 11: Slice into individual sliders and serve warm.
