Mix together the ground beef and roasted garlic. Form the mixture into four balls, and flatten into patties about 3/4 inch thick. Sprinkle the patties with garlic pepper, lemon salt, and Cajun seasoning.
Lightly oil the grilling surface. Place onions on the grill, and toast on both sides. Place beef patties on the grill, and set the onions on top of them. Grill for about 5 minutes on each side, or to desired doneness. If you're lucky (or trashy) enough to still have a coffee can of grease on your stove, brush both sides of the Hawaiian rolls, then toast them on the grill.
To assemble, place the patties on buns, and top with slices of American and Edam cheese, lettuce, tomato, pickles, and your choice of condiments such as ketchup, Creole mustard, and salad dressing. These listed are some of mine.
