These tasty hamburgers have spaghetti sauce in the ground beef and they're topped with Mozzarella cheese. Serve on lightly grilled Kaiser rolls or onion rolls for a delicious alternative to plain old hamburgers.

• 1 pound lean ground beef
• 1/2 cup spaghetti sauce
• 1 mild sweet onion - sliced thin
• 2 T. melted butter
• 4 thick slices mozzarella cheese
• 4 kaiser rolls or onion rolls

Preparation -
Add the tomato sauce and seasonings to the ground beef. Mix well, let stand for about 10 minutes, then shape into 4 burger patties. Grill for about 5 to 6 minutes per side, or to desired doneness outside and totally free of any trace of pink in the center. While burgers are grilling, brush thin slices of onion with 1 T. melted butter and grill lightly. Brush sliced sides of buns with melted butter and grill lightly. Just before removing burgers from grill top each with a slice of Mozzarella. Place on burgers on grilled buns and top with grilled onions. Add a small amount of additional spaghetti sauce, if desired.
