Preheat oven to 350 degrees F.
Spray a 9x13" baking pan with cooking spray.
In the middle of each tortilla, spread ~2 tablespoons of mashed potatoes. The measurements here are very rough. If you'd like more mashed potatoes, add more. Just kind of estimate to your liking.
Top with a couple spoonfuls of stuffing, some turkey, and green beans.
Roll up and place seam side down in the baking dish until the baking dish is full.
Cover with gravy and sprinkle with cheddar cheese.
Bake in preheated oven for 25-30 minutes, until cheese is melted.
Serve topped with leftover cranberry sauce.
