In a large pot, add chicken and fill the pot with enough water to cover the chicken by an inch. Add 1 tablespoon of salt and a teaspoon of pepper.
Bring to a boil and reduce heat so that the liquid is still simmering - just hot enough for bubbles to barely break the surface. Cover pot and continue to cook for about 8-10 minutes, or until a meat thermometer reads 165 degrees.
Meanwhile, in a large bowl, combine pesto, Greek yogurt and ½ teaspoon salt then set aside. Rough chop the sun-dried tomatoes.
Once cooked, remove chicken from the pot and allow to cool. Chop into ½-inch pieces - or adjust the size as you prefer.
Add chicken and sun-dried tomatoes to the yogurt/pesto mixture, and combine thoroughly.
Rinse/dry lettuce, then build sandwiches to your liking using the sun-dried pesto chicken, lettuce, and Sprouted Grain bread!
