Preheat the oven to 350 F.
Cook your chicken breast until well done (50-70 minutes depending on the thickness of your chicken breast), and juices run clear if you haven't done so already.
Once your chicken has cooled, shred your chicken using two forks or a hand mixer, until finely shredded.
In a medium-sized mixing bowl, mix together using a hand mixer, cream cheese, and greek yogurt.
Blend in your buffalo sauce, jalapeno, half of the shredded cheese, green onion, and parmesan cheese.
Add your chicken and stir until well combined.
Spray a rectangular baking dish with oil.
Evenly layer in your dip mix using a spatula or the back of a spoon.
Top with remaining cheese and parsley for garnish.
Bake on 350 F for 20-24 mins uncovered until the cheese has browned and the dip is bubbling.
