preheat oven to 400F
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 1/4 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.
