Preheat your oven to 450 degrees f. and line a large sheet pan with parchment paper.
Slice your peppers in half lengthwise and remove the seeds. Place the pepper halves, cut side up, on your prepared sheet pan.
In a medium bowl, combine all the filling ingredients and stir well. Taste test and add more hot sauce or Greek yogurt to your desired taste and consistency.
Stuff each pepper half with the chicken mixture and lay on the sheet pan with a bit of space in between.
Sprinkle lightly with shredded cheese.
Roast in your preheated oven for 8-10 minutes, or just until the tops start to brown.
Remove from the oven and add your favorite toppings.
Enjoy while hot!
