1Combine shredded parmesan and shredded mozzarella in a bowl.
2In a separate bowl, mix garlic powder, onion powder, italian seasoning, salt, and black pepper, then sprinkle the spice mix over the combined cheese and mix well.

4Top each cheese pile with a little shredded rotisserie chicken.
5Bake in a 425 degree oven.
6Prepare the Caesar salad kit in a bowl while the cheese shells bake.
7Remove the cheese shells from the oven, let them cool slightly, then stuff each one with the prepared Caesar salad.
