Quick, tasty & frugal - Tortilla Española (Spanish Omelette)

I wanted to whip up a quick lunch yesterday and was going to make an omelette when I remembered there was half a *tins worth of potatoes in the fridge to be used up.  I love Spanish Tortilla so it was a bit of a no-brainer decision what to do with them.
This is quick, easy and cheap yet satisfying and a bit more of a meal than just an omelette would be.  In fact really this makes enough for a snack later too.  As the Spanish generally advocate serving it at room temperature this is most definitely not a problem for me!
So - what do we need?

1 small onion, halved and sliced finely
Half a tin potatoes- use the value ones
2 eggs
EVOO
Fresh parsley
S+P

Heat a slug of EVOO and sweat down the onions whilst you slice the potatoes.  You can make them thick or thin - it' a matter of personal choice. I've seen recipes for both ways on line and they all claim that theirs is the 'authentic' way of doing it.
Add the potatoes and a pinch of salt and cook gently, half covered, until nicely softened, getting a little colour and taking on all the lovely oniony flavours.
Beat the eggs, add plenty of salt and pepper and pour swiftly into the pan.  Throw in the chopped parsley and give the whole lot a very quick stir so everything is coated in the egg, then cover and leave to cook.
Once you judge the bottom is cooked through, cover the pan with a plate and quickly invert the lot, then slide the tortilla back in to finish cooking.
Serve.  That's all there is to it.  J

You could add other bits to this depending on what you have lying around to use up.  You could also add another egg for an even more substantial final product if wanted.  It's one of those very un-strict recipes.  Have a play with it!

*I don't normally use tinned potatoes but had wanted to experiment with them for my lunch at work.  Our work kitchen is woefully under equipped - there's a coffee maker and a boiling water tap and that's it.  No microwave, toaster, kettle, anything of that sort.  This can make it a bit of a challenge (and one I embrace) to come up with hot food for lunch in the winter.  One day I might get round to a mini-series of posts on 'cooking without a cooker' or something along those lines.

I'm adding this to Chris's Bloggers Around the World - Food World Cup challenge.  Do check it out - there's going to be a lot of posts for this one!
