This a recipe that my family enjoys. To save time, I'll sometimes use seasoned chicken breast strips. You can also add sliced black olives, if desired.
Cook chicken and shred. Mix together the soup, green chilis and onions. Cut tortillas in wedges. Layer crockpot with 1/3 each of the sauce, tortillas, soup and chicken mix and cheese then repeat two times ending with cheese on top.
Cook in crockpot on low temperature for 4-5 hours.
