The word "watercress" may bring to mind dainty tea sandwiches and ladies wearing hats. However, watercress has much more to offer. A dark and shiny green, watercress (nasturtium officinale) is a leafy green in the cabbage family. Its relatives include collards, kale, mustard greens and endive. Like many leafy greens, watercress is high in vitamin C and iron.

Watercress grows prolifically along small flowing streams. One should be careful about harvesting wild watercress, as bacteria and parasites present in these streams may be harmful. Fortunately, safe sources of watercress are available at many farmers' markets and grocery stores.

If you purchase watercress at the grocer or market, it will most likely come in a bunch. To wash it, leave the bunch held together by a rubber band and plunge into a sink or basin of cold water and swish around, then drain and pat dry on a clean towel. Watercress can be torn into pieces and added to salads for a peppery bite, or sautéed and served warm. Watercress grows almost year round in maritime climates, so anytime is a great time to add watercress to your dinner, salad, soups and, yes, even to your sandwiches.

Or try this delicious salad featuring watercress. The recipe can easily be adapted to include other seasonal vegetables as well.
