2 cups uncooked elbow macaroni pasta
8 ounces cheddar cheese, grated
2 cans (10.5 ounces each) condensed cream of chicken soup
1 cup milk (I used 2%)
1 cup chicken broth
1 lb. uncooked boneless, skinless chicken breasts, diced
1 cup finely-diced onion (I use frozen chopped onion as a shortcut)
1 (4 ounce) jar diced pimentos, drained
