1Cut chicken into strips, about 2x1/4 inch. In 3- to 4-quart saucepan, stir chicken and chicken seasoning (from jambalaya mix) until chicken is evenly coated; stir in oil. (For best results, use saucepan with nonstick finish.)
2Cook chicken uncovered over medium-high heat about 8 minutes, turning chicken over after 5 minutes, until dark brown on both sides. Stir in hot water, sauce mix and uncooked rice (from jambalaya mix), tomatoes and sausage. Heat to boiling, stirring occasionally. Reduce heat; cover and simmer about 25 minutes, stirring once, until rice is tender.
3Stir in peanut butter. Cook about 2 minutes longer or until mixture is thickened. Cover; let stand about 5 minutes or until most of liquid is absorbed.
