"I live alone, so I'm always looking for ways to use up leftovers like beef,' explains Barbara Zowada of Sheridan, Wyoming. 'This soup makes a quick lunch or dinner along with fresh veggies or a crisp green salad.'"
Prepare soup according to package directions; add beef. Ladle into two 2-cup ovenproof bowls. Top each with a French bread slice. Sprinkle with Monterey Jack cheese and Parmesan cheese if desired. Broil until cheese is melted. Serve immediately.
