"I just made this today for a "mother/daughter lunch" to impress my mom (who is Martha Stewart-ish) and it was DELICIOUS!!! I used frozen spinach instead of fresh, and added ~1 c. mozzarella on the very top, and used rotisserie chicken instead of sauteeing in olive oil. As for the reviewers who were disappointed with the quantity of bechamel sauce, I have to say that their layers must have been very thin, as I used all of the sauce and it filled a nice 9 x 13 with an inch to spare without boiling over. I am a firm believer that anyone can cook if they can read, and when a recipe says it calls for SEVEN cups of milk, etc, you need to plan your pans accordingly. I prepared the sauce in a dutch oven-type of pan to accommodate all the ingredients in one pot. This recipe was easy to prepare, was presented in a step--by-step manner, and was absolutely fabulous-tasting! I will definitely make again for a sure-fire crowd-pleaser!! Enjoy!"
