Swede and Parsnip mash

I really fancied sausage and mash last night, but I didn't have any potatoes and this close to the end of the month I couldn't afford to buy any. What I did have in the fridge though was half a swede and some parsnips.

Ingredients (serves 1 greedy person)
1/2 a swede (200g approx)
1 parsnip
Knob of butter
Salt/pepper

* peel the veg and cut into even chunks
* bring a pan of water to the boil, and the veg and cook for around half an hour, or until soft
* drain, then put the veg back into the pan and return to the heat for 30 seconds or so to get rid of excess moisture
* add a knob of butter to the pan, with a pinch of salt and plenty of pepper
* mash the veg 
* eat!

I think I actually prefer this to potatoes.
