▢ 1 1/2 - 2 pounds thinly sliced, fully cooked beef tenderloin, chopped we prefer medium-rare, room temperature
▢ 12 ounce pkg. King’s Hawaiian Original Sweet Rolls, 12 count
▢ 4 ounce shredded cheese I used Jalapeno Havarti, may substitute any cheese preferred, such as provolone or cheddar
▢ 1/3 cup crispy onions, such as Fresh Gourmet brand optional
▢ 1/4 cup butter, melted

In a medium mixing bowl, combine the ketchup, mayonnaise, mustard, Worcestershire sauce, relish and horseradish; stir until sauce is well blended, then reserve.
1/2 cup mayonnaise, 1/4 cup ketchup, 2 tablespoons Worcestershire sauce, 2 tablespoons spicy brown mustard, 3 tablespons sweet pickle relish, 1 teaspoon prepared horseradish

In a large skillet over medium heat, add a good swish of olive oil. When the oil is nicely hot, add the onions to the skillet, along with the Worcestershire sauce.
olive oil, 3 medium red onions, 1/4 cup Worcestershire sauce
Cook the onions until they soften and caramelize, adding a bit of liquid (such as broth, wine, or water) to the onions as they cook to keep them moist, if needed. Reserve and keep warm.

Preheat the oven to 350 degrees F.
Leave the sheet of Hawaiian rolls intact; slice the entire sheet in half horizontally, separating the top from the bottom. Place the bottom sheet into a 9x13 pan or onto small rimmed baking sheet.

Spread the bottom sheet of rolls with an even layer of the warm caramelized onions; top with the chopped beef tenderloin then drizzle as much of the prepared sauce over the beef as desired.

Sprinkle with shredded cheese and fried onions (if using), then top with the top sheet of rolls; brush with melted butter.

Bake the sliders for 12-15 minutes, uncovered, on the center oven rack until hot throughout and the top buns are a deep, golden brown.
Let the sliders cool slightly, then transfer the entire sheet to a large cutting board and slice it apart. Serve at once.
