Boil 2 inches water in large pan. Add 2 large organic chicken breasts. Cook on high until water is halfway evaporated. Turn heat on medium to low. Brown and remove. Let cool. (Please note: poaching 2 large breasts of chicken will take approximately 20 minutes.)
While chicken is cooking or cooling, chop red onion and grape tomatoes into small pieces. Break feta cheese into small clumps.
