what are the round disc things you refer to? Ha! I found it! You can buy the disks at Bed, Bath & Beyond-type stores (at about half the price you see listed here): The green disk thingy I'm getting some tomorrow! I agree with the bagged people. I usually eat salad for lunch, and only if I eat a ton of it each day will it not go to waste. As a matter of fact, i just threw out about 1/4 of a bag (this is after eating it for 3 days in a row)...
