PREPARATION: 

Light Cowboy Hardwood Lump Charcoal in a charcoal chimney and let burn for 10-15 minutes

Spread hot coals over one side of grill and preheat grill for approximately 10 minutes

Place medium sized skillet on grill and melt butter. Add mushrooms and onion. Cook and stir for about 5 minutes until mushrooms have softened. Let cool

In a medium bowl, mix together ground beef, salt and pepper

Measure twelve 1/4 cup portions of beef and shape them into 4-inch round patties. Place 1 tablespoon of both mushrooms and cheese into the center of six of the patties. Place remaining six patties on top, pinching the edges to seal the filling

Place patties on grill over medium heat for 4-6 minutes per side, or until they are cooked through. For medium, burgers will reach internal temperature of 160 degrees farenheit

Place buns on grill for about a minute to lightly toast the edges

Remove from grill and let cool
