I sort of ad-libbed on this, browning the meat in a large non-stick frying pan first and adding all the ingredients there before transfering to a baking dish and adding the noodles. This was great because I could check the flavoring as I went along. I found it a bit bland in flavor, so I added tabasco sauce to taste, before baking.
Now keep in mind I live in Southern California, so my idea of bland may be just fine for most people! I served with a spoon of sour cream on each serving and found it to be very enjoyable!
