In a small pot, bring the barley and water to a boil.
Reduce to a boil, cover and cook for 20 minutes.
Serve immediately or refrigerate and serve chilled.
Notes
If you can't find roasted barley, you can make your own by roasting the barley in a nonstick skillet over medium heat for 5 to 10 minutes, or until the grains turn a dark brown color.
