Season chicken breasts with the Italian seasoning, salt, and lemon pepper. Grill for 5-6 minutes on each side, or pan-fry for about 7 minutes on each side or until juices run clear. Let cool then slice into 1/2 inch strips.
Whisk together dressing, honey, and olive oil. Toss dressing, using only a tablespoon or so at a time to avoid over-dressing, with grapes, gets, peanuts, onion, and spinach.
Serve salad and top with sliced chicken breasts. Enjoy!
