We celebrated Ken's birthday today and he wanted hamburgers. Amazingly, after years of grilling up meats, this is the first time I have ever done hamburgers. We bought pre-cut patties from Costco that still needed to be formed into burgers this morning--so fresh we had to wait for them to come out of the grinder and packaged! After squishing them down to about 2/3 inch flat round discs, the only other thing I did was to lightly season them with garlic salt.
Some patties came out bigger than others, which worked out perfectly since some of us ate less than others. After about 6 minutes on one side, I flipped the patties over and at the same time added the buns to the upper grill rack to cook for about another 4 minutes before adding a slice of Muenster cheese to each patty. As soon as the cheese melted, the burgers were ready. I sandwiched each patty between buns and let our guests build their own burgers with the usual fixings.
*We had them for dinner again the next night and I made a wasabi aioli for mine.
