Preheat the oven to 400 degrees F. Grease a baking sheet. Place the tortillas on a work surface. Place 1/4 cup of the cheese on the top half of each tortilla. Add 1 tablespoon of the bacon and one tablespoon of green onion. Fold the tortillas in half, pressing gently to seal them closed. Place the folded tortillas in a single layer on the baking sheet. Place the baking sheet in the oven and bake at 400 degrees F for 8-10 minutes or until lightly browned. Remove from the oven and cut into wedges. Serve hot.
