When bacon is cooled, chop the bacon up into small pieces. Set aside.
In a large bowl, mix your ground beef and bacon together. Make sure to incorporate the bacon throughout all of the ground beef.
Add salt and pepper to taste.
Form the beef mixture into 3 inch balls. You can make the balls bigger or smaller depending on the size of burger you would like.
Use you thumb and make an indention in the center of your beef ball. This will be where you will place your cheese. Put enough cheese to fill this void that you created.
Once the cheese is in this opening, form the beef mixture on top of the cheese. You can do this by "folding" the beef over the cheese. If you would like, you can also add a little more beef to cover up the cheese. It is very important that you make certain that you seal the cheese in the middle of your beef ball. Very lightly pat your beef ball into a patty. You want to try and keep the patty slightly on the thicker side as it will produce a more juicy slider in the end.
Place your sliders on a hot grill and cook to your liking. I myself prefer my burgers a little on the pink side, but I cook them more well for the kids. Either way, they are delicious.
Notes
For a perfect fit, use heat and serve dinner rolls for the sliders. Prepare rolls according the packaging. Once cooled, cut the rolls in half and toasted on the grill. You can use any type of buns that you like. I think that a potato roll or even a regular hamburger bun would be suitable as well. Tomatoes, onions, lettuce, pickles, avocado,ketchup, mustard, mayonnaise, relish........the possibilities are endless of what to top these little patties of goodness.
