Classic slit pea soup with ham. On my first attempt, the ham was too salty. This time I let the ham stay in cold water for half a day and the result was wonderful. a simple recipe. Just buy a large slice of cooked ham in the meat department and reduce it's salt content. As for the rest, put celery, carrots and onions along with well soaked split peas and the rest is easy. A very hearty dish.
