There are many slightly altered versions available that you can choose or modify from that will yield good outcomes. One change may be to use tuna, BBQ lamb, rotisserie chicken, swordfish, beef steaks. You can also easily substitute many of the ingredients in order to suite your taste. Aceto balsamico is excellent as a topping for many different recipes and foods.
