Mexican Casserole - Weight Watchers

"This is a very different variation of "Mexican Casserole - 6.5 Weight Watcher Points". This is a little easier and quicker and I wanted to see the nutritional info on it. This is a great WW recipe as it's high in fiber, low in fat and is very filling. This can be OAMC as it freezes and reheats well after cooking. I havn't tried freezing before cooking though. It could also easily be made vegetarian simply by subbing the hamburger for another type of bean or meat substitute. Edited to add that these are *very* large servings and I calculated them to be only 7.5 points each if calculated using only 4 servings...."
