The default is to always give info on a 100 g "edible portion." You can add columns appropriate to the food (e.g., for "scallion" you might pick "1 medium" in addition to 100 g).
It is hardly all-metric (a medium scallion is specified as 4-1/8" long), but apparently built around the fundamental portion of 100 grams.
I also noticed in the March/April 2003 issue of WeightWatchers magazine, in an advertisement for free range buffalo meat (www.purenaturemeats.com), in a nutrition table comparing buffalo, beef, pork and chicken, portion sizes are listed as "compared in 100 gram portions (about 3.25 oz)".
Perhaps this "100 g edible portion" will start becoming more of a "standard" in the world of nutrition, supplanting ounces.
