Put the chicken in a pot and cover it with water. Bring it to a boil and let the chicken cook for 5 minutes. Now move the pot to a cool burner, put the lid on and let it sit for 30 minutes (the chicken will continue to cook while it sits in the water.) Remove the chicken and shred it into bite sized pieces.
Combine chicken in large bowl with oil and oregano. Cover and marinate for one hour.
Bring another pot of water to a boil. Add the green beans and simmer until the beans are done, from 3 to 6 minutes depending on how crisp you like your beans. Drain under cool running water until they are cool.
Add the green beans to the bowl with the marinated chicken, add some lemon juice, capers, cherry tomatoes and crumbled feta cheese. Toss and season to taste with salt and pepper. You’re done!
