What is the traditional form of breakfast potatoes that are either shredded or chopped before cooking?

The traditional form of breakfast potatoes that are either shredded or chopped before cooking is hashed browns. Hashed browns are typically made from potatoes that are grated or finely chopped, and then cooked on a griddle or frying pan until they are crispy and golden. This method of preparation allows the potatoes to develop a nice texture and flavor that is often associated with breakfast dishes.

Other types of potato preparations, such as roasted, cubed, or mashed potatoes, do not fit the description given in the question. Roasted potatoes are usually cut into larger pieces and cooked in the oven, while cubed potatoes involve cutting into cubes, which can vary in size and are not necessarily associated with breakfast. Mashed potatoes, on the other hand, are boiled and then whipped or mashed into a smooth consistency, which is distinctly different from the crispy, textured presentation of hashed browns. Thus, the characteristics of hashed browns align perfectly with the criteria provided in the question.
