This is a lot like the original tater tot casserole i made. This is a really good basic recipe. The nice thing about tater tot casseroles is that you can leave as a major comfort food, or you can jazz it up to make it "big kid" food. I have made this with every vegetable combination under the sun. Sometimes I mix cream of chicken with the mushroom. I also like to saute mushrooms and carrot matchsticks with the onions when I brown the meat. But like i said, this is really good as written too!
