  • Toast French bread rolls, cut side up. Add white cheddar cheese, melt.

  • Divide caramelized onions and roast beef, pile both sandwiches high, top with the other half of the bun and enjoy!
  • In a small saucepan, combine beef consomme with fresh rosemary. Allow to simmer for 5-10 minutes so the flavor develops. Remove sprig and test for taste. Add pepper, if desired and needed.
