Chicken is placed in a crockpot. Cover with mixture of salsa, dijon mustard, and splenda brown sugar. Cook on low for approx 6 hours. Use to forks to shred the chicken after it is cooked. During the last 30 minutes of cooking, after shredding chicken, add beans and corn.
(IDEA, next time add 1 cup Rotel in place of 1 of the cups of salsa.) Serve over 1/2 cup cooked rice for each serving.
