Preheat the oven to 350°F and line a baking sheet with parchment paper or a silicone mat.

In a large skillet over medium-high heat, cook the ground beef until fully browned. Drain any excess grease.

Reduce the heat to low, stir in the can of Manwich, and let the mixture simmer for about 5 minutes to heat through and blend the flavors.

While the meat simmers, slice the Hawaiian rolls in half horizontally with a serrated knife, keeping the top and bottom halves intact.

Place the bottom half of the rolls onto the prepared baking sheet.

Spread the sloppy joe mixture evenly over the rolls, making sure to cover the entire surface.

Lay the cheddar cheese slices over the meat.

Add the top half of the rolls to close the sliders.

In a small microwave-safe bowl, melt the butter. Stir in the brown sugar, Dijon mustard, and Worcestershire sauce until fully combined.

Brush the butter mixture evenly over the tops of the rolls.

Sprinkle sesame seeds over the top.

Bake uncovered for 20 to 25 minutes, until the tops are golden brown and the cheese is melted.

Let the sliders cool slightly, then transfer them to a cutting board. Garnish with chopped parsley if desired.

Slice along the seams to separate into individual sliders and serve warm.
