Raise the heat to high, cover, and bring to a boil. #3. Once boiling, reduce the heat to medium, then simmer for 5 minutes. Stir in the orzo, 1 teaspoon salt, and black pepper to taste. Simmer another 5 minutes. Then turn the heat off. #4. Using tongs, remove the two chicken breasts from the pot. Use a fork and the tongs to shred the chicken. Then place it back in the pot.
