Roast Beef Sliders on Hawaiian Rolls

Peel and thinly slice the onions.

Cook in olive oil over low heat until caramelized.

Mix together the mayo, sour cream, horseradish and salt and pepper for the horseradish cream.

Slice the slider buns in half horizontally (use a serrated knife), keeping the buns together.

Spread the bottom half of the buns with horseradish cream.

Top the roast beef with the caramelized onions.

Layer on the slices of cheese to cover completely. Let them fall over the sides slightly.

Spread on another layer of horseradish cream, then top with crispy fried onions (optional).

Add the tops of the buns, then press down slightly.
