I can't recall where the references were, but I asked the Sonoma dietitian about olives last year. I vaguely remember being told that olives were allowed in small amounts as flavor enhancers without counting towards your fat. You wouldn't want to sit down and much them from a bowl, lol, but it's ok to add them to recipes. However, if you do want to sit and munch, 15 olives equals 1 1/2 tsp of fat.
Capers would be free
