In the United States, pea soup without qualification usually means a perfectly smooth puree. Split Pea Soup is a slightly thinner soup with visible peas, pieces of ham or other pork, and vegetables (most commonly carrots) and is usually made from dried, green split peas.
Rather, the field pea is the new protein star. Field peas are grown for the purpose of drying, not to be eaten fresh, and can be either green or yellow.

Pea protein is often combined with rice protein in products to make a complete protein. [See Why These Famous Vegetarians and Vegans Pass on Meat.].
