Heat your grill to medium high heat. Grill the chicken tenderloins for about 7-10 minutes, turning once, until an internal temperature of 165 degrees is reached. Alternatively, you can cook them indoors using a grill pan or George Foreman Grill.
Combine the dressing ingredients in a small jar with a lid. Shake well.
Place the salad greens on two plates. Top with the grilled chicken, sliced apple, and blackberries.
