Bubble 'n squeak with a fried egg on top.
Or fry up with bacon/pancetta, garlic, caraway seeds and savoy cabbage. You could swap the caraway seeds for walnuts. A dollop of brown sauce won't go amiss.

Patatos bravos with chorizo in a garlic and tomato sauce.
Eat them cold, on their own (but dip in salt first).
