Cabbage and Kielbasa

This is easy and cheap! I like serving it with fresh fruit.
1-2 T. oil
1 large onion, chopped
about 10 c. shredded cabbage
about ½ pound kielbasa, cut
Salt and pepper

In a large skillet, cook onion in oil until tender. Add cabbage, season with salt and pepper. Place kielbasa on top. Cover with a tight-fitting lid and cook on medium-low until cabbage is tender as desired, stirring occasionally.
