Pour in the broth, stirring to deglaze the pot. Stir in the remaining ingredients.
Bring the stew to a boil, then reduce the heat to medium low. Cover the bowl, and continue simmering the soup until it's thick and the barley's cooked, 30-45 minutes. Make sure to stir occasionally. to prevent sticking, and stir in the peas the last 10 minutes or so. Remove the lid the last five minutes, and let some of the moisture cook out if it's not thick enough yet.
