Shred chicken and place in a large bowl. Set aside half of the chopped green onions and shredded cheese. In a separate bowl, combine all other ingredients until mixed well. Gently fold in chicken. Fill each flour tortilla down the center with a chicken mixture. Fold over the sides of each tortilla approximately one inch on each side and then roll length-wise. Spray a 9 X 13 glass baking dish with non-stick spray and add the tortillas to the baking dish.If you have extra filling you can spread that evenly over the top of the tortillas. Next, cover the tortillas with shredded cheese. Cover tightly with foil and bake covered at 325 degrees for 45 minutes. Uncover for the last fifteen minutes until bubbly and browning on the sides of the dish. Remove from oven and let rest for fifteen minutes. Garnish with sliced green onion, slice, and serve!
