Greens are a New Years tradition in the South, but I cook them more often than that. The Wife and kids love them.
Buy a huge bag (they will cook way down) and remove any large stems. Soak them over and over moving them from one large bowl to another. You can be simmering (with enough water to cover) a couple Smoked Ham Hocks (or Country Ham Chunks) with some crushed red pepper in a small pot at this time. You can tear/cut the greens into lengthwise strips about an inch thick at this time.
Simmer the pork for about 30 minutes and put it and the broth from the small pot into a very large pot. Take the heat up to a boil and add the greens - force them into the pot and cover. You can drop the heat to simmer after they cook down a bit. Simmer for about 45 - 60 min. (they will look like cooked spinach)
Serve with a vinegar pepper sauce like Texas Pete and Corn Bread.
