Spartan, instead of getting a smoked ham hock, find a fresh ham bone.
Take 2 quarts of chicken stock and put it in a stock pot with the ham bone. Simmer for 2 hours or so.
Render some diced bacon until just under crisp. Sautee a diced chopped onion with bacon until tender. Add a few cloves of diced garlic for a few more seconds then add a pound of fresh peas, the stock, bone and all, and a few leaves of chopped mustard greens. Season with salt amd pepper. Simmer about 45minutes to an hour. Adjust salt if necessary.
