1 onion
400g cold potato mash
150g leftover Brussels sprouts, broccoli or carrots
45g butter
2 tbsp flour
2 tbsp oil
4 eggs
a dash of vinegar
4 slices of smoked salmon
chives, chopped
salt and pepper
Makes 4 patties for 2-4 people
Peel and slice the onion. Heat 10g butter in a large frying pan and fry the onion with a pinch of salt for 8 minutes in until browned and really soft.
Put the mash in a large bowl and add the onions to it. Finely chop the leftover vegetables and add to the bowl. Season generously with salt and pepper and mix.
Shape the potato mixture into 4 patties and dip each side of the patties into a bit of flour.
Heat the oil and remaining 35g butter in the frying pan used for the onions. Fry the potato patties on a medium heat for about 8 minutes on each side until browned and crispy.
Meanwhile, poach the eggs one at a time. Bring a saucepan of water to the boil, then turn down to a simmer. Break one egg into a small cup. Pour the vinegar into the simmering water and give it a swirl, then carefully slide the egg in to the water. Cook the egg for 1.45 minutes, then remove with a slotted spoon and put on a plate. Repeat with the remaining eggs.
Put the fried potato patties onto 2 or 4 plates, top each with a slice of smoked salmon and with a poached egg. Sprinkle with chopped chives and serve.
TIP: You could use ham or fried bacon instead of smoked salmon
