Melt the margarine in a very large sauté pan over medium heat. Add the jalapeno peppers, garlic and onions. Add the cabbage until the pan is full. You may not be able to fit all the cabbage in the pan at first, but you can add more as it cooks down. Sauté, stirring often, for 15 to 20 minutes or until all the cabbage is tender and transparent. Season with salt and black pepper to taste.

Cook noodles al dente, according to package instructions. Drain well and transfer to a large serving bowl. Add the cabbage and mix well. Serve piping hot.
