It's wheat grass I think, or maybe some sort of bean-sprout..
OK, I broke down and just did a google search, here it are the ingredients.
Traditionally, the seven items are sekeh (coin); samanu (a sweet wheat pudding); sabzi (green sprouts); sonbol (hyacinth flower); seer (garlic); senjed (dried wild olive); and serkeh (vinegar). The various items symbolize justice, good thoughts, good deeds, prosperity, virtue, immortality and generosity. In addition, there are goldfish, colored eggs, a mirror and candles.
By the way, does anyone remember my old avatar with Isfahan in the background, maybe I should put it back up.
