Add the split peas, ham bone, and enough water to cover ingredients; season with salt and pepper.
Cover, and cook until there are no peas left, just a green liquid, 2 hours. While it is cooking, check to see if water has evaporated. You may need to add more water as the soup continues to cook.
Once the soup is a green liquid remove from heat, and let stand so it will thicken. Once thickened you may need to heat through to serve.
