Rinse the farro first in a fine mesh strainer. Fill a medium pot with 3 cups of water and add 1/2 teaspoon of salt. Add the farro and bring the water to a boil. Immediately turn the heat to simmer. Cover and cook. Cook for 40 to 45 minutes.Drain off any excess water and place the farro into the refrigerator to chill while you prepare the rest of the salad.
Make the Salad
Add all the veggies to a large bowl. Add the chilled farro, lemon juice, parsley, olive oil and remaining salt and mix to combine. Add the feta last so it will keep its shape in the salad. Place the salad in the fridge to let all the flavors marry together before serving.
