Carefully slice each chicken breast into two chicken cutlets. If you're using tenders, you can leave them as-is.
Combine the oil and seasonings in a large food storage bag, place the chicken inside, seal the bag and move the pieces all around inside the bag, to evenly coat them. Marinate the chicken for 2 hours, or at least for 20 minutes.
Preheat the broiler to 450 degrees farenheit.
Cook farro according to package directions.
Lightly grease a sheetpan and broil the peppers for 7-10 minutes, turning as needed, to allow all sides to blister. The skin will blacken, but we will be peeling that layer off later.
Prepare tahini dressing by combining the ingredients in a small bowl or jar, and whisking thoroughly.
Add the chicken to the sheetpan with the peppers and place back under the broiler. Broil for 4 minutes, and then using tongs, flip the chicken to broil on the other side for an additional 4 minutes. Flip the peppers as needed.
The blistered peppers will peel easily. Gently pull the outermost layer of skin right off the pepper, and discard.
Prepare bowls with a bottom layer of farro and top with broiled chicken and sweet peppers. Add more chopped parsley and a sprinkle of salt and pepper.
