Pea Soup
Pea soup or split pea soup is soup made typically from dried peas, such as the split pea. It is, with variations, a part of the cuisine of many cultures. It is most often greyish-green or yellow in color depending on the regional variety of peas used.
Pea soup has been eaten since antiquity; it is mentioned in Aristophanes' The Birds, and according to one source "the Greeks and Romans were cultivating this legume about 500 to 400 BC. During that era, vendors in the streets of Athens were selling hot pea soup."
