- In a 5-quart kettle or pot, melt margarine and brown chicken until well-browned on all sides. Remove the chicken and keep warm.

- Remove the chicken; add the corn and lima beans and cook for another 30 minutes.
- Cook pasta separately while the chicken is cooking.
- Skim the fat from the soup. Remove the skin and bones from the chicken; cut into bite-size pieces. Return the chicken to the pot; add the cooked pasta shells.
