The flavors of a chilled gazpacho soup make a refreshing salad on a warm summer evening.
Heat grill to medium-high heat. Rub chicken with seasoning. Place chicken on grill; cover. Cook for 20 to 30 minutes, turning once, until no longer pink near bone.
Meanwhile, mix all salad ingredients except watercress in medium bowl. Serve salad on watercress with chicken.
Nutritional values may change if you choose to substitute another chicken product.
Fresh baby arugula leaves would be a terrific substitute for watercress if you find some at the farmers market or in your own garden.
