Instructions

  1. Step 1: In a medium saucepan, melt 2 tbsp butter over medium heat. Whisk in 2 tbsp all-purpose flour and cook for 1 minute to form a roux.

  4. Step 4: Spread 1/2 tbsp softened butter on one side of each bread slice. Place two slices butter-side down on a plate.
  5. Step 5: Layer ham and turkey evenly over bread, then spread 1/4 cup Mornay sauce over meat.
  6. Step 6: Top with remaining bread slices, butter-side up, and press gently to secure.
