Instructions
In a small bowl, whisk together olive oil, balsamic vinegar, lemon juice, dried oregano, ground mustard, salt, and pepper. Place the chicken in a resealable bag and add about ¾ of the vinaigrette. Seal bag and marinate chicken for 1 hour up to 4 hours.
Heat a grill or grill pan to medium high. Remove the chicken from the vinaigrette and grill for about 5 - 6 minutes per side for the boneless breasts and 3 - 4 minutes per side for the tenderloins. Remove from grill/pan and cover with foil to keep warm.
In a small bowl combine the tomato, cucumber, and olives and add the remaining ¼ of the vinaigrette. Toss to coat.
To serve, top grilled chicken with the olive and tomato salsa and some of the crumbled feta.
