3. Rinse rice under cold water until clear.
4. In a medium saucepan, combine rice and water. Bring to a boil, then lower heat, cover, and simmer for about 15-20 minutes until fluffy.
5. In the same skillet used for chicken, add sweet corn and diced red bell pepper. Sauté for about 5 minutes until tender but crisp.
6. Slice rested chicken into bite-sized pieces and return to skillet with corn and peppers.
7. Squeeze fresh lime juice over the mixture and stir gently.
8. Fluff cooked rice with a fork and divide among bowls. Top each bowl with the chicken-corn mixture and garnish with sliced green onions.
