Mashed Potato Quesadillas

2 cups mashed potatoes
6-8 slices cooked bacon, crumbled
1/4 cup sliced green onions
8 flour tortillas
2 cups shredded Cheddar cheese
1 cup salsa
1/4 cup sour cream

Stir together mashed potatoes, bacon and green onions and warm in a skillet until heated through. Spread mashed potato mixture onto 4 tortillas, spreading to within 1/2 inch of the edges. Sprinkle the shredded cheese on top of the mashed potatoes and top with the remaining tortillas. Spray each side of quesadilla with cooking spray.
Preheat a large skillet over medium heat. Place a quesadilla into the preheated pan, and cook until golden brown and crispy, then turn over and continue cooking on the other side until browned, 2 to 3 minutes per side. Repeat with remaining quesadillas. Serve with salsa and sour cream.
