Lay the cheese slices over the buns.
Top the cheese with sliced onions.
Place thinly sliced roast beef over the onions.
Add the top half of the buns to the sliders.
Pour the mustard mixture over the sliders.
Bake on 350°F for 10-15 minutes until the cheese is melted and the top is golden brown.
Enjoy hot with a side of au jus.
