Yum! Very easy and very good!
I used non-fat yogurt and half the butter, so the texture wasn't so creamy. I wouldn't use non-fat yogurt again but I would use half the butter again. I ended up with a lot of extra sauce, but I don't know how much chicken I used, so my porportions were off. If I added enough chicken for all the sauce, like double, it seems it would make way more than four servings, maybe more like eight. Not that that really matters. This is all going to get eaten! I served it over jasmine rice and it was perfect.
I totally forgot the cilantro, but I'll use it on the leftovers, which I am very much looking forward to.
Thanks, MKitty, for a great recipe. The long lead time (two hour soak for the chicken) could make this hard to do on work nights, but I'll most definitely be making this again.
