Slice the potatoes into ¼ inch circles then cut each of those in half. Next rinse and place them into a medium-size glass bowl. Sprinkle the potatoes with ½ teaspoon salt and ¼ teaspoon black pepper, stir or toss with your hands. Microwave the potatoes for 4 minutes, stir and microwave an additional 2-4 minutes until fork tender.
While the potatoes are cooking, warm a large skillet over medium-high heat. Add the butter and once melted, add your peppers and onions. Saute for a few minutes, until the onion is almost translucent and the peppers are softened. Add the garlic and the kielbasa. Cook while stirring frequently, for about 3 minutes.
After the potatoes have been cooked in the microwave until tender, add them to the skillet. Mix them together with the vegetables and sausage. Drizzle on a little oil only if needed. Spread the potatoes across the pan and allow them to cook for 2-3 minutes, stir and continue cooking until lightly browned.
Add the chopped cabbage to the pan and sprinkle with seasoning salt (and pepper to taste). Toss to combine and reduce heat to medium-low. Cover with lid. Cook for about 2-5 minutes more, until the cabbage is cooked to your liking.
