Sweet potato and chorizo hash- great weekday supper

ALTHOUGH this does involve grating sweet potato, which is a bit of a chore, it is a pretty tasty weekday supper. And doesn't need lots of ingredients.

Serves 2
Ingredients:

Sweet potato, 1 large, peeled and coarsely greated
Onion, 1 chopped
Olive oil
Hot cooking chorizo, 1 large or 2 small, skins removed and crumbled or chopped
Creme fraice 4 tbsp mixed with the zest and juice of 1 lemon
Rocket 1 small bag

Method:

*Mix the sweet potato and onion. Put a good slug of olive oil in a frying pan and add the chorizo and cook until it releases some oil and crisps up. Add the potato, mix and season. Fry, turning the mixture over for 5 to 10 minutes, or until it is cooked through. Press it down with your spatula and leave for a few minutes to get crunchy on the base. Divide between two plates and spoon some creme fraiche onto each, serve with rocket.
