I started with this (http://p2.hostingprod.com/@thaikitchen.com/heatservesoups.html#)
(the first entry) as my base...

To it I added, 1/4lb sliced sirloin pork, 1 HUGE crimini mushroom, 1/2 a jalapeno, a VERY small amount of cut garlic, and a bit of onion as well.

Then I added my favorite sauce, Taste of Thai: Garlic CHili Pepper Sauce (I cant stress this enough people, its the best ever)...then my secret...PEANUT BUTTER! Now I know what you're thinking, "Andrew, you added peanut butter to a soup?!?!" WHy yes, yes I did. It dissolves and it gives a really great flavour..in fact I recommend this for nearly all soups.

Salt, pepper, low heat covered for 30 min. until pork is tender, and you're done...take that Rachel Ray! :)

Soon I'm going to look up a recipe for the broth itself, but I was lazy tonight.

I forgot to add 2 things...
I estimated this to be about 350 calories (80 for the broth according the package, 200 for my 1/4 sirloin, and I used about 1/2-1tablespoon of peanut butter which is about 90 calories..the rest was the veggies).
Also, be sure to remove the lemongrass from the broth, its strickly for flavor and if you try to eat it you'll be really sorry..the package says to remove it and they aren't kidding around.
