Step 1

Preheat oven to 450 degrees.

Step 2

Combine chicken, shredded cheese, and olives in a medium bowl. Set aside.

Step 3

Butter one side of each of the 8 slices of bread.

Step 4

Sprinkle 4 of the bread slices on the buttered side with some Parmesan cheese, and place them butter side down on a baking sheet.

Step 5

Distribute filling across the 4 slices.

Step 6

Sprinkle remaining Parmesan cheese on the buttered side of the last 4 slices of bread, and place them on top of the filling, buttered side up.

Step 7

Bake for 6-8 minutes, then flip the sandwiches and bake about 6 minutes more, until the sandwiches are golden brown and crispy. (Alternatively, you can grill them on the stove top on a griddle or in a skillet).
