To Assemble the Sandwiches:

• Place 4 slices sourdough on a cutting board, plate, or other flat surface.
• Divide 2 tablespoons honey mustard into four ½-tablespoon portions. Spread ½ tablespoon honey mustard evenly across the top side of each slice of sourdough.
• Divide 2 slices white cheddar cheese in half, creating 4 slices of cheese total. Place one “slice” of cheese on each piece of bread, covering honey mustard.
• Divide 4 slices deli turkey into 2 slices of turkey per sandwich. Place turkey slices on top of 2 slices of cheese-topped bread.
• Divide ½ cup fresh baby spinach into ¼ cup spinach per sandwich. Layer preferred number of thin tomato slices and ¼ cup baby spinach on top of each layer of turkey.
• Divide 4 strips cooked beef bacon into 2 slices of beef bacon per sandwich and place each portion of beef bacon on the remaining slices of cheese-topped bread.
• Close sandwiches, placing sandwich halves with beef bacon face-down on top of sandwich halves with turkey. Each sandwich should consist of the following layers:
  1 slice sourdough
  ¼ tablespoon honey mustard
  1 half-slice cheese
  2 slices deli turkey
  Thin tomato slices
  ¼ cup baby spinach
  2 strips beef bacon
  1 half-slice cheese
  ½ tablespoon honey mustard
  1 slice sourdough.

To Warm the Sandwich:

• Divide 2 tablespoons butter into four ½-tablespoon portions. Spread ½ tablespoon butter on the outside of each slice of bread (4 sides total).
• Place a large skillet on the stovetop over medium heat. When the pan is warm, carefully place assembled sandwiches flat in the skillet.
• Toast the bottom slice of bread for 3 to 4 minutes, then carefully flip the sandwich over. Toast the now-bottom slice of bread for 3 to 4 minutes, or until the cheese has melted and the sandwich is warmed through.
• Transfer sandwiches to serving plates. Serve warm with desired sides.
