Don't give up on your beloved Thanksgiving turkey. Make this giant sandwich from your leftovers!
Preheat oven to 350° and grease a bundt pan with cooking spray. Place bread dough into the bottom of prepared pan and pinch together ends to form a ring.
Bake until golden on bottoms and cooked through the 25 to 30 minutes. Let cool 5 minutes, then invert onto a wire rack to cool completely.
In a small bowl, whisk melted butter, garlic powder, oregano, and a pinch salt until combined. Slice bread in half to make two layers. On a large baking sheet, place one-half cut-side-down and the other cut-side-up. Brush both pieces all over with butter mixture. Bake until lightly toasted, about 10 minutes.
In a medium bowl, whisk mayo, lemon juice, herbs, paprika, and a pinch of salt until combined. Spread over bottom half.
Top with turkey, stuffing, potatoes, spinach, and cranberry sauce. Drizzle with gravy then sandwich with top half of baked bread.
