South-of-the-Border Bake

We use this regularly, with the addition of 1/2 lb to-1 chicken or beef (precooked), served over rice it makes a great single dish meal that everyone likes. My children have been eating this since they were first introduced to it when I found it in 1996. Stands the test of time. Also easy to scale up. Can bed prepared ahead of time and baked later. I have also prepared it ahead and reduced the cooking temperature to 250 F which allows be to stretch the cooking time to up to 2.5 hours which allows me to take kids to soccer and come home to a healthy ready to eat meal. There is lots of moisture from the zucchini but I usually cover the baking pan with foil if I bake it this long to prevent over cooking of the top layer.
