In a medium saucepan, combine the broth with the potatoes, tomatoes, beans and onions, and season with salt and pepper. Bring to a boil, and then reduce the heat to medium. Cook the soup until the potatoes are tender, 20 to 25 minutes. Remove from the heat, stir in the corn and serve. Adjust seasoning as needed.
