Leftover Potatoes or Fries
Leftover cooked potatoes or fries (odd but it happens!), make a potato omelette.
Heat a tbsp oil in a frying pan.
Scramble a couple of eggs with a splash of milk and a dash of salt and pepper in a bowl.
Chop the potatoes into cubes (roughly 1cm or so) and mix them into the egg mixture.
Pour into the frying pan and cook through. Flip it so as to cook both sides.
