Preheat An Outdoor Grill For High Heat, And Lightly Oil The Grate. Mix The Ground Beef, Worcestershire, Garlic, Onion, Salt, And Pepper. Shape Into 6 Thin Patties. Cook On The Preheated Grill Until The Burgers Are Cooked To Your Desired Degree Of Doneness, About 3 Minutes Per Side For Well Done. An Instant-Read Thermometer Inserted Into The Center Should Read 160 Degrees F (70 Degrees C). Place The Cheese Slices On The Burgers During The Last Minute Of Cooking. Heat The Can Of Chili In A Saucepan Until Hot. Cut The Hamburger Patties In Half And Put Two Halves Into A Hot Dog Bun, Side By Side. Place The Pickles In The Buns And Top With Chili.
