Heat a pot of water to boiling and then cook the egg noodles or pasta until just done, drain and then set aside. A small amount of olive oil drizzled on the noodles will keep them from sticking.
In a large non-stick pan, heat a splash of olive oil and cook the smoked sausage until lightly browned, if cooking home made sausage, cook until cooked through.
Is using smoked sausage, you may need to add another splash of olive oil then add the butter, onion, and garlic, cooking until the onion is soft. OR if using home made sausage, you may need to drain off some of the fat but leave a little in the pan then just add the butter, onion, and garlic and cook that until the onion is soft. About 5 minutes or so, stirring once in a while.
Add the cabbage and cook until tender, stirring often, maybe 15 minutes or so then add in the peas, noodles or pasta and salt and pepper to your liking. Cook this until heated through, just a few minutes then serve.
