This recipe has been around for a while. It is delicious casserole that can be made ahead time, if needed. The only thing I can add to this is a few of my personal preferences when making this recipe. Maybe they will be yours too. :) I like to use the brand Ro-tel tomatoes with MILD green chilies. If you like hot, by all means use the original. We just like the mild flavor better. Also, I like to mix the whole tomatoes and the diced tomatoes in a blender for just a few seconds just enough to break up the tomatoes a bit but, this is not necessary. I just like my tomatoes broken down a little more, yet not saucy. I also have used either sour cream or PLAIN yogurt in this recipe and both are equally good in my opinion. Same goes for the use of Monterey Jack cheese or Mozzarella cheese. We like the taste of either of those two cheeses in this recipe as well.
