Preheat the oven to 350 degrees F.

In a large bowl add ground beef, salt, pepper, garlic powder and egg. Mix ingredients until fully combined.

Divide the meat in half to form two rectangles. Be sure these rectangles are a bit bigger than your set of 12 connected dinner rolls. You are forming rectangles so that once cooked you can place the meat rectangle on top of the dinner rolls

Place both rectangles on a cookie sheet and if you like onion you can add some minced onion on the top here to allow it to cook with the meat

Bake for about 12 minutes. Since tastes vary you can cook it less or more depending on how done you would like the cheeseburgers.

Open your set of sliders and spoon a couple of tablespoons of Thousand Island dressing on each of the slider bottoms and evenly spread it over all rolls with a spoon.

Once the meat is done, place the meat patties on each of the bottoms of 12 buns. Then spread dressing on top of both of the meat rectangles.

Place cheese slices on top of the meat and place it back in the over for a couple of minutes to allow the cheese to melt.

Once the cheese has melted top the burgers with minced onion, pickles and lettuce. Then top it with the top of the slider buns.

Spread the melted butter over the tops of the slider buns and sprinkle the sesame seeds.

Cut the sliders into individual cheeseburgers and Enjoy!
