Salmon Frittata

2 tbsp olive oil
1 large onion - sliced
6 large eggs
300g cold cooked potatoes - cut into cubes
200g cold cooked spinach - chopped (or peas/broad beans)
1 tbsp chopped parsley
2 fillets salmon (grilled), broken into large flakes*
75g cheddar cheese, grated
Salt and freshly ground black pepper

(*Firstly grill the salmon and let cool.)

Heat the olive oil in a non stick frying pan and add the onion. Cook until soft and golden. Meanwhile beat the eggs lightly and season well.
Add the potatoes to the onion and cook gently for a few mins to heat them through, stir in the spinach, parsley and flaked salmon. Add some seasoning, make sure ingredients are well combined and evenly distributed in the pan. Then pour in the eggs. Keep pan on low heat & keep it still to let the egg solidify slowly from the base up. After 7mins shake the pan a little.
Sprinkle the cheese on top & place the pan under a moderately heated grill until the top is set and golden brown.
Serve with salad.
