POTATOES WITH CHORIZO (PATATAS A LA RIOJANA)

This is a straightforward winter (heavy) lunch meal.
You need:
150 gr chorizo cut in 1 cm slices (try to buy good chorizo as the cheap versions are full of fat)
250 gr potatoes in chunks
2 table spoons in olive oil
a clove of garlic (cut thinly)
1 onion (cut thinly)
1 tb spoon of sweet paprika
salt
water
Heat the olive oil in a large frying pan (do not make it too hot, just a little). Add the garlic and wait for a minute or so until it is golden. Then add the onion - reduce the heat and let it fry for 10 minutes until the onion is translucent ane a little golden. Then add the chorizo and wait for 10 minutes (if you want this with less fat heat the chorizo for 30 seconds in a microwave oven first) Afterwards add the potatoes and continue frying (over medium heat) for 10 minutes. Add salt and the paprika and cover the whole lot with water. Continue heating the pan until the water boils and then reduce the heat. Let it simmer for 20 minutes until the potatoes are soft and the sauce becomes thick. Serve.
It is very easy for the kids to help with this. We practiced cutting the potatoes in chucks by chipping them rather than making straight lines - they enjoyed the noise they made.  Chorizo is always a winner with my children.
