Ingredients

Serves 2 sandwiches

For the gravy dijon mayo:

  • 1/3 cup mayo my goto is KEWPIE
  • 3 tbsp leftover turkey gravy cooled
  • 1 tsp Dijon mustard
  • Salt and freshly cracked black pepper to taste

For the turkey salad:

  • 1 1/2 cups leftover cooked turkey loosely shredded
  • 1/4 cup finely diced apple Honeycrisp or Granny Smith
  • 2 tbsp finely diced celery
  • 2 tbsp finely diced red onion
  • 3 tbsp gravy Dijon mayo from above
  • Salt and pepper to taste

For the sandwich assembly:

  • 4 slices sourdough bread
  • 1/2 cup leftover mashed potatoes
  • 1/2 cup leftover stuffing
  • 1/4 cup cranberry sauce
  • Remaining gravy Dijon mayo
  • Butter or olive oil for toasting bread

Instructions 

  • Make the gravy Dijon mayo: In a small bowl, whisk together the mayonnaise, cooled leftover gravy, and Dijon mustard until smooth and creamy. Season with salt and pepper to taste. Set aside a few tablespoons for assembling the sandwiches.
  • Prepare the turkey salad: Loosely shred the leftover turkey into bite-sized pieces. Add to a bowl with the diced apple, celery, and red onion. Fold in 2–3 tablespoons of the gravy Dijon mayo until everything is lightly coated. Season with salt and pepper as needed.
  • Toast the sourdough: Lightly butter or drizzle the sourdough slices with olive oil. Toast in a skillet over medium heat until golden and crispy on both sides. Meanwhile, gently reheat the mashed potatoes and stuffing until hot throughout.
  • Assemble the sandwiches: Spread the remaining gravy Dijon mayo on the inside of each slice of toasted sourdough. On the bottom slices, layer the warm mashed potatoes, stuffing, and a generous portion of the turkey salad. Spoon the cranberry sauce over the turkey, then top with the remaining sourdough slices.
  • Serve: Gently press down on each sandwich to hold the layers together. Slice in half and serve immediately, with extra warm gravy on the side for dipping if desired.
