Preheat your oven to 350°F. This way it’s ready to go once your sliders are assembled.

In a large skillet over medium heat, add the ground beef, diced onion, and chopped green pepper. Cook, breaking up the meat with a spoon, until the beef is browned and the vegetables are tender, about 2 to 4 minutes.

In a measuring cup or small bowl, whisk together the ketchup, Worcestershire sauce, salt, pepper, cornstarch, and beef broth until smooth.

Pour the sauce mixture into the skillet with the beef. Stir to combine, then cook for 3 to 5 minutes, or until the mixture thickens slightly. Remove from heat.

While the meat mixture finishes cooking, use a serrated knife to slice the Hawaiian rolls in half horizontally, keeping them connected if possible. Place the bottom halves in a half sheet pan or a 9x13 baking dish.

Spoon the beef mixture evenly over the bottom rolls. Layer the provolone or American cheese slices on top, then add the top half of the rolls.

In a small bowl, mix the melted butter and minced garlic. Brush or pour it over the tops of the rolls.

Cover the pan loosely with foil and bake in the preheated oven for 20 minutes, or until the cheese is melted and the tops are lightly golden.

Let cool slightly before cutting. Serve warm—and maybe make a double batch, because these go fast!
