Split pea soup is classic comfort food. This version is a basic combination of green split peas, ham, vegetables, and seasonings. This basic pea soup is cooked on the stovetop, but with just a few alterations, it may be cooked in the slow cooker. If you like a smooth pea soup, reserve the diced ham and blend all or part of the soup in batches* when it's done. Add the ham and heat through. Top this soup off with a little finely chopped ham, crumbled bacon, or crunchy croutons.
