In a Large Skillet over medium heat, brown hot dogs in oil for 2-3 minutes or until lightly browned. Remove with a slotted spoon. In the same skillet, saute onion and green pepper until tender.
In a small bowl, combine the soup, cream and onion mixture. Place potatoes in a greased 11-in. x 7-in. baking dish; sprinkle with salt. Top with hot dogs. Pour soup mixture over all. Bake, uncovered, at 350 for 30-35 minutes or until heated through.
