Brush chicken breasts with olive oil, sprinkle with Mrs. Dash® Southwest Chipotle Seasoning Blend. Heat grill, place chicken on grill and cook 4 minutes per side, basting when turned. Chicken is cooked when juices run clear. Meanwhile, add mandarin oranges and grapes to lettuce, and toss with salad dressing. When chicken has cooled, cut into 1/2" strips. Place grilled chicken on top of lettuce, sprinkle with slivered almonds.
