This is was a big hit at our Thanksgiving 2008 card night.
12 oz Pepper Jack Cheese grated the “kick” comes from this so if it is not enough add some crushed red pepper flakes
8 oz Mozzarella grated
16 oz Frozen Spinach, thawed and as much water removed as possible
10 oz of chopped Artichokes
1 cup Mayonnaise
1/4 cup Parmigiano-Reggiano Cheese, you can use the green can crap, but I wouldn’t recommend it.

Mix everything, except Parmigiano,  together in a bowl.  Add Salt and Pepper to taste.
Place everything in oven proof dish heat at 350 until hot and gooey.  Sprinkle Parmigiano cheese and broil until golden brown and delicious.  I served mine with corn chips but this will manage with just about anything.
