Add the mozzarella cheese, almond flour, and cream cheese to a microwave safe bowl. Microwave for 1 minute, stir, then microwave for 30 seconds more. Stir until combined and not too hot to touch, then stir in the egg and knead until the egg is completely combined.
Spread the dough out onto a piece of parchment paper. Press the dough out with your hands until it is ¼ inch thick. Place the parchment and pizza crust in the oven and bake for 10 minute. Pop any bubbles that form in the crust while baking.
Remove the crust from the oven and spread with the olive oil and parmesan cheese. Bake an additional 5 minutes. Remove from the oven
While the crust is baking, toss the lettuce, chicken, and dressing to make the salad.
To serve, pile the caesar salad on top of the fathead crust and slice.
Notes
I like to use Newmans Own creamy Caesar. You could also make your own.
Chop the lettuce and the chicken into small pieces so it is easier to eat on the pizza.
To make this without a microwave: Add the mozzarella, cream cheese, and almond four to a sauce pan on the stove over medium heat and cover with a lid. Let cook until the cheese is just melted. Remove from heat and stir until everything is combined. Pour into a bowl and let cool until you can knead it with your hands. Add the egg and knead until completely combined. Place on a piece of parchment paper and press into a round or oblong shape ¼ inch thick.
