One Skillet Corned Beef Hash

2 tablespoons vegetable oil

2 onions, chopped

4 potatoes, peeled and chopped

2 (12 ounce) cans corned beef

1 tablespoon ground black pepper

5 tablespoons cider vinegar

Heat oil in a large skillet over medium high heat. Saute onions and potatoes until slightly browned, then stir in corned beef.

Partially cover skillet, reduce heat to medium-low and cook, stirring occasionally, for about 20 minutes or until potatoes are tender.
