Place the farro and water in a saucepan and bring the liquid to a boil over high heat. Lower the heat, cover the pan and simmer for about 30 minutes or until the farro is tender, but still chewy. Set the farro aside to cool slightly. Cook the carrots in boiling water for 3-4 minutes or until tender. Drain and add to the farro. Add the peas and tomatoes and toss the ingredients to distribute them evenly. In a separate bowl or a jar, combine the olive oil, lemon juice, dill and lemon peel. Whisk the ingredients until well combine (or shake in a covered jar). Pour into the farro mixture and toss the ingredients. Season to taste with salt and pepper.
