Smoked Salmon Hash

1 or 2 tablespoons olive oil
400g leftover boiled potatoes, roughly diced
Pinch of paprika or chilli
1 egg very lightly beaten
3-4 tomatoes, roughly chopped
150g smoked salmon, torn into pieces

Heat the olive oil in a large frying pan, then add the potato.  Cook until beginning to brown.  Keep the potatoes moving round the pan so that they do not burn.  Add more oil if needed.  Season with sea salt and freshly ground black pepper, and stir through the paprika or chilli.  Add the egg and continue stirring to mix through, add the tomatoes and when they begin to soften, mix in the smoked salmon.  Remove from the heat and check for seasoning.
Serve immediately.
