The dressing may solidify in the refrigerator. It is best to allow dressing to sit on the counter. Shake well before using. If you are making the salad ahead, prep the salad ingredients and refrigerate. Then dress the salad about 15 minutes before serving. This will help keep the spinach from wilting. Mozzarella, feta or goat cheese are also amazing on this salad. Lighten it up by subbing plain pecans for the candied ones and eliminate the sugar from the dressing. Add sliced grilled chicken for a fabulous summer meal.
