Add Garlic salt to each slice(if you like it more salty, add a little more).
Layer each slice with the Parmesan then with Mozzarella on top of that.
Italian Seasoning on the very top.
Bake at 400 F for about 5 minutes, then switch to broiler for a couple additional minutes. This will help it brown nicely and bring out the flavor in the Italian Seasonings; which is why it's important it is on top.
