1/2 cup sugar
1/2 cup red wine vinegar
1/2 cup olive or canola oil
1 garlic clove, minced
1/2 tsp. salt
1/4 tsp. pepper
2 lbs. boneless skinless chicken breasts
6 cups torn romaine
6 cups torn red leaf lettuce
1 pint fresh blueberries

Whisk the first six ingredients in a large bowl.  Pour 3/4 cup marinade into a large resealable plastic bag; add the chicken.  Seal bag and turn to coat; refrigerate overnight.  Cover and refrigerate remaining marinade.  Drain and discard marinade.  Grill chicken, covered, over medium heat for 5-8 min. on each side or until juices run clear.  Cut into strips.  In a large bowl, combine lettuce, blueberries, strawberries, cheese and walnuts.  Add reserved marinade; toss to coat.  Top with sliced chicken.  Makes 9-10 servings.  This recipe is from Simple & Delicious magazine.
