Smoked Mackerel and Beetroot Frittata

This was a delicious fritttata, it's along time since I've made one, but this was definitely a success. Yummy!

Smoked Mackerel and Beetroot Frittata (from The Times)
(Serves 1)

1 cooked beetroot, diced
1 smoked mackerel fillet, flaked
oil
3 eggs
1 tsp sage

Preheat the grill to high. Heat the oil in a small frying pan, add the beetroot and smoked mackerel and cook for 2-3 mins.

Whisk the eggs in a bowl and season with salt and pepper. Pour them into the pan, making sure all the ingredients are well spread out and are covered by the eggs. Sprinkle over the sage and cook over a medium heat for about 4 mins, until the underside is cooked.

Transfer the pan to the grill and cook for 4 mins, until the eggs have set. Serve.
