Ingredients

• 32 ounces 100 percent ground sirloin
• 12 strips bacon
• 1 tablespoon butter
• 4 kaiser egg buns
• 1 recipe Blue Cheese Spread, recipe follows
• 1 recipe Sauteed Mushrooms, recipe follows
• 4 lettuce leaves
• 4 tomato slices
• 4 red onion slices
• 1 1/4 cups crumbled blue cheese
• 3/4 cup sour cream
• 1 tablespoon butter
• 1 tablespoon minced garlic
• 8 ounces sliced mushrooms
• 2 ounces white wine

Instructions

1. Form the ground sirloin into 4 (8-ounce) patties. Over an open-flame, grill each burger to desired temperature. While the patties are grilling, cook bacon until desired crispness, and set aside.
2. Butter both sides of each bun and grill until toasted. On each of the 4 bottom buns, place the burger, followed by the blue cheese spread, mushrooms, and bacon, in that order. On each of the top 4 buns, place the lettuce, tomato and red onion, in that order. Top with any additional condiments desired, sandwich the 2 sides, and serve.
3. Combine both ingredients in a bowl and refrigerate for 2 hours prior to use.
4. Melt butter in a large saute pan over medium heat. Add garlic and mushrooms and saute until tender. Add wine and simmer for 1 minute or until almost evaporated. Remove from heat and set aside until ready to use.
