This is super quick and delicious. The only thing I'd do differently is add some jalapeno peppers to make it spicier. It's a great way to use the bottom of the tortilla chip bag. The tortilla chips make a crispy crust on the bottom of the casserole. I skipped the garnishes and it still tasted great. Recipe courtesy of Chris Gavenda, Wildwood, MO and www.epicurious.com.
