Preheat oven to 375 degrees. Spray 9×13 pan with Pam. Lay out crescent rolls in 4 sections on waxed paper. (Keep the triangles together to form a rectangle). Put shredded chicken and cheese on rolls and roll them up (like a short burrito). Mix cream of chicken soup and milk and heat on stovetop in a small pan until fairly smooth. (add any leftover chicken or cheese to this). Pour between crescent rolls in pan. (Be careful to pour around, not on top or they will be mushy!). Bake in oven for 15-20 minutes or until crescent rolls are cooked through and brown on top.
