For a fun and healthy appetizer, skip the cheese and crackers and try edamame instead. The soybean, which East Asians have enjoyed as a source of protein for more than 2,000 years, has gained popularity in the United States and is a staple on most sushi restaurant menus. Though you can purchase edamame beans already shelled, for picnic purposes, it's probably best to go with the variety still encased in their pods for portability -- think of it as a convenient, built-in food delivery device. Bags of frozen edamame pods are available in the freezer section of most grocery stores near other vegetables, and cooking them is a breeze. Just drop the desired amount into boiling water for five minutes or so, drain, and cool. And the extra bonus? A half a cup of shucked beans comes in at just 100 calories and 2.5 grams of fat.
