Preheat grill to medium heat.

In a bowl combine ground beef, onion, salt, bread crumbs and egg. Mix with hands until everything is incorporated together.

Make 12 patties.

When ready to grill, brush the grill grate with oil to keep the sliders from sticking. Place the sliders on the grill and cook for 4 minutes. Turn the sliders over and cook for another 4 minutes until medium rare (or cook longer if you prefer them more well done).

For the last 2 minutes of cooking time, brush on 1/2 tablespoon of barbecue sauce, add 1/3 piece of bacon on top of sauce, add 1/4 piece of cheese on the top of each slider and close the grill lid until cheese has melted.

Remove the sliders to a platter and ENJOY!
