Great with a back yard beer.
Sprinkle the patties with salt and pepper. If you’re grilling, preheat your barbecue to medium-high. Otherwise, set a large, heavy skillet over medium-high heat and get it nice and hot. (Add a drizzle of vegetable oil, if you like.)
Place the burgers on the grill or skillet, close the lid or cover loosely with a piece of foil, and cook for about 5 minutes.
Flip and cook in the same manner for another 5 minutes. (Don’t press down on them, or you’ll squeeze the juices out.)
Turn the heat off, leaving the burgers on the grill or skillet, and place a piece of cheese on top of each. Close the lid or cover for a few minutes, until the cheese melts. Serve on buns, with your choice of condiments.
