In a large pot or deep frying pan, bring the oil or butter up to medium heat and render a bit of the fat from the bacon.
Add the onion, cabbage, and garlic (and carrot if you're using it) to the pan and cook, stirring occasionally, just until the onions start to turn translucent, about 3 to 5 minutes.
Add the sausage, salsa, Worcestershire sauce, hot sauce, salt, and sugar to the pan, and give it a few gentle stirs to incorporate all the ingredients.
Reduce the heat to medium low, cover, and simmer for 20 to 25 minutes.
Sprinkle green onions and/or cilantro over the top and serve with starch of choice.
Enjoy! :)
