Heart Attack Burger Recipe

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Divide the beef in half and form each half into a patty. Grill the beef patties for 8 to 10 minutes per side or to desired doneness.

While the burgers are grilling melt 1/4 cup of butter in a large skillet. Lay out 4 slices of bread and top each slice with 2 slices of American cheese. Top each sandwich with a slice of bread to make 4 cheese sandwiches. Pan-fry the sandwiches in the butter until golden brown about 3 minutes per side. Set the sandwiches aside.

Melt the remaining 2 tablespoons of butter in the skillet and cook the sliced onions until browned stirring occasionally about 8 minutes.

To assemble top each grilled burger with half the onions and place each between 2 grilled cheese sandwiches.
