Mushroom Stuffed Burgers

Ingredients:

• 1 1/2 pounds lean ground beef
• 1/4 cup finely chopped onion
• 2 eggs, slightly beaten
• 3/4 cup soft bread crumbs
• 1/4 cup ketchup
• 1/2 teaspoon salt
• 1/8 teaspoon pepper
• 2 tablespoons butter
• 8 ounces sliced mushrooms
• 6 slices Cheddar, Mozzarella, or American cheese
• 6 split buns, toasted

Preparation:

Combine ground beef, onion, eggs, bread crumbs, ketchup, salt, and pepper; shape into into twelve thin (about 1/4-inch thick) patties. In a skillet, melt the butter and sauté the mushrooms until just tender. Place mushrooms on 6 of the patties. Top with remaining patties and seal edges. Broil or grill the burgers to desired doneness. Top each with a slice of cheese and let melt. Serve on split toasted buns.
