Preheat your oven to 425 degrees F and line a baking sheet with parchment paper.
Combine the canned chicken, egg, Parmesan, and spices in a large bowl. Mix it until everything's nicely blended together.
Transfer the mixture to the prepared baking sheet, pressing it into a thin, even layer in the shape of a pizza base.
Pop it in the oven for about 28-35 minutes, or until it's golden brown and crispy. Let it cool slightly before adding your toppings.
Toss the greens in Caesar dressing until they're well-coated. Add a bit of Parmesan and toss again.
Top your crispy chicken crust with the salad mixture. Garnish with more Parmesan, croutons, and a drizzle of lemon juice if desired.
