Preparation:
In skillet, sauté mushrooms, onion and garlic in butter until tender, about 2 minutes; set aside.

Spread to within 1/2 inch of edge. Top with the remaining 6 patties; seal edges.
Place patties on grill about 6 inches over medium coals.
Grill 10-15 minutes, turning once. Serve on buns, if desired. |
