Wash the cabbage and cut out the core. Next cut cabbage into thin slices.
Heat cast iron skillet and fry the bacon. Remove bacon to a plate covered with a paper towel to drain. Do Not Throw Dripping In Skillet Away!
Add summer sausage to bacon drippings and heat for approximately 3-4 minutes. Remove from the grease to the paper towel.
Next add your onion to the grease and cook for about 1-2 minutes until soft. Add cabbage and stir together. It will be piled pretty high in the skillet, but that's ok, it will cook down.
Stir cabbage and onion regularly.
Once the cabbage cooks down a good bit, approx 6-8 minutes, add sausage and mix together. Cook for 2 minutes more.
Next add your crumbled up bacon to the mixture, stir together and cook for 2-3 minutes more.
Season with salt and pepper to taste.
***Cabbage has a strong odor when cooking*** To help eliminate odor while cooking, add a couple tablespoons of apple-cider vinegar to cooking cabbage. It will not affect the taste of your cabbage.
