- 8 slices American cheese
- 2 tablespoons white sesame seeds
- Preheat the oven to 350 F.
- Melt 2 tablespoons butter in a skillet over medium-low heat.
- Add the onions to the pan. Cook them for about 10 minutes, or until they are very soft and golden. Remove the onions from the pan.
- Cook the ground beef in the same pan until browned, stirring to break up the clumps. Season the cooked beef with salt and pepper.
- Slice Hawaiian rolls horizontally through the middle, creating 1 large bottom bun and 1 large top bun.
- Place the bottom buns (ideally still in 1 piece) on a sheet pan and top them with the onions.

- Cover the burger with the top bun layer.
- Melt the remaining butter and brush It over the buns. Sprinkle on the sesame seeds.
- Bake until the buns are browned and the cheese is melted.
- Remove the pan from the oven. Pull the super-slider apart into individual servings or allow the guests to as they serve themselves.
