Milwaukee Beer and Onion Burgers

Directions:

1. Preheat grill to medium.
2. In large bowl mix together ground pork, beer, hot pepper sauce, Worcestershire sauce and salt and pepper to taste.
3. Form into four large patties, about 1/2 inch thick, handling as little as possible.
4. Meanwhile, in a large heavy skillet, sauté onion slices in butter over medium-low heat, stirring occasionally, for about 20 minutes, until onions are soft and start to caramelize; keep warm.
5. Grill patties directly over fire until nicely browned on both sides, for a total of 12-15 minutes, until an instant read thermometer reads 160ºF.
6. Serve on buns topped with sautéed onions.
