Quick Thai soup

On Thursday I celebrated my birthday in a Thai restaurant with a few friends, and had very yummy food:)
The next day though, I wanted some more Thai prawn soup:D
I made some tonight with a few simple ingredients... It wasn't as fantastic as Baan Thai's one, but it still hit the spot.

So here's the recipe (makes about 5 bowls of soup):

1 red pepper
a bit of leek white (a spring onion would do nicely too)
2 big handfuls of fresh spinach
some rice noodles (I used a 2-3 people "wok-ready" pack, I'm guessing about 250g)
about 300g prawns (I used pre-cooked prawn tails)
1 or 2 chillies
my Asian food "usual suspects" (oyster sauce, fish sauce, soy sauce, toasted sesame oil and lime juice)

1. Slice the red pepper and the leek as finely as possible and sauté in a pan.
2. Boil about 5 bowls of water (yes I actually poured bowls of water in the pan to get a better control on the final quantity - I always make too much food!), add the sauces and chillies to taste.
3. Add the fresh spinach, let it wilt (it should only take about a minute), then add all the rest to the pot.
You're done!

Now that was easy:)
The verdict: I had to add a bit more soy sauce and lime juice to mine, and thought it was pretty mild, but the BF found it quite spicy! (He's still not used to spicy food).
