What is your go-to way for making quesadillas?

Okay I've been CRAVING chicken quesadillas!!!!

What is your go to way of making them? Just chicken and cheese? Do you add beans and salsa in tortilla? Or put on top? Onions and olives in tortilla or as garnish or neither? Sour cream and salsa as garnish????? ADD taco seasoning to chicken or plain? Guacamole or avocado?
