This is so easy, and so yummy! I served it with tortilla chips and sour cream, told them it was a "dip" and even my nacho/taco-hating 7 y.o. LOVED it! But it wasn't so soupy that it couldn't be eaten as a casserole. I used extra sharp cheddar, and found I could use even less than 2 cups - maybe 1.5 cups - therefore making it a bit "healthier". A definite winner in our house, and it will be made again and again!
