A staple in my home. I tried to make a green bean casserole at Thanksgiving this year and was read the riot act by the boys and told to make this instead. Can be a side or meal of its own when served with potatoes.
Place a large Dutch oven on the stove at med-hi heat. Add the bacon fat. Add the green beans and onion. Sauté until the onion is translucent, constantly stirring to coat the beans. They will turn a brighter green in the fat.
Add the water or ham broth and ham pieces. Bring to boil then turn down to low and simmer until the beans are tender and the liquid is reduced. Approx 20 mins. If the water evaporates faster than the beans are cooking, adjust by adding water. If there is far too much liquid and the beans are cooking faster than it evaporates, do not cover. Final dish should still be moist but not have a lot of loose liquid. Salt and pepper to taste.
