There are a million versions of spicy peanut sauce - this is just another take on an old (?) favourite. It uses vinegar which I like because I don't always have citrus on hand. My 3 year old loves this (go figure), it's just the right amount of spice for him - so of course you might want to beef up the chili. I also went pretty light on the sesame oil to try and save some calories...all in all it's pretty tasty and super easy! In my photo I had stir-fried it with some buckwheat noodes, bok choi, broccoli and some other veg. Note that it only makes 1/2 a cup, about enough for 2.
