To make blueberry dressing: In blender, process blueberries, balsamic vinegar, honey, lemon juice, olive oil and salt and pepper, to taste, until smooth. Set aside.
To prepare salad: Cut apples into 1/4-inch thick slices. Using 1-1/2-inch diameter star-shaped cutter, cut apple slices into stars.
Place lettuce mix in large bowl; add apples, strawberries and blueberries. Sprinkle with pecans. Before serving, drizzle each salad with blueberry dressing.
