don't really ever eat salads because the toppings just aren't worth it to me.. but if I do, I use either white balsamic or raspberry balsamic vinegar... sometimes I will cook with the vinegar and throw the veggies and/or chicken that I cooked it in, all on top of the salad.. when you cook with the vinegar, it does tend to thicken, and the acidity of it is lessened... makes it a little more enjoyable...
