I didnt come up with this recipe and have no idea where I got it...but didnt see it in here so...

(kinda gotta wing the amounts...I go based on how it looks)

4 cooked chicken breasts (cut up for easier processing)
3 eggs
1/2 cup parmesan cheese
garlic, basil, etc (italian seasonings) that appeal to you
(i use alot of garlic & basil)

Combine all ingredients in a food processor or blender and puree until you've got a fairly goopy thick liquid.
(I use the blender because I dont own a processer)

Rub a cookie sheet (stoneware is the best) with olive oil (or spray pam on it) and pour mixture into pan spreading so that it's an even thickness.

Bake until light brown & firm ~ 350

Now...two options:
1) add your toppings and bake until cheese looks done for a whole pizza
or
2) slice into squares and top as you need them ~ I usually do this because then you also have the option of using the squares as bread for sandwiches.

Wish I knew where I got this so I could give credit...suffice to say it's not mine but I use it all the time.
