A southern classic, this is my husband's favorite greens. It may not be the exact way that all southern cooks prepare their greens (because nobody taught me how to cook them,) but it is my own recipe and is delicious, especially alongside black-eyed peas and cornbread. It's great for the traditional New Year's meal to bring good fortune!
Place frozen greens, chopped onion & ham hock (or diced ham) in a dutch oven or stock pot.
Fill pot with enough water to generously cover, but not so much as to boil over.
Add freshly ground black pepper to taste.
Bring to boil, over medium-high heat, stirring occasionally to separate the frozen greens. When greens are all separated, reduce heat to medium-low, cover with lid & let simmer for 2 hours or more, checking liquid level occasionally. You may remove lid during last half hour of cooking, if desired, to reduce liquid (you may need to increase heat to medium.)
Taste for seasoning; add salt and pepper as needed.
Serve hot with chopped egg and cider vinegar for each serving.
