Preheat the oven to 400ºF.
Season the chicken breasts on both sides with salt and pepper.
Heat the olive oil in a large, oven-safe skillet or cast iron over medium heat. When the oil is hot, add the chicken breasts to the pan and cook for 5-6 minutes on each side.
Remove the chicken from the pan when the internal temperature reaches 165ºF.
Add the cottage cheese to a high-speed food processor or blender. Blend for 4-5 minutes until completely smooth and whipped. Add the Greek yogurt and hot sauce. Blend until smooth.
Shred the chicken and then transfer it back into the same pan. Add the cottage cheese mixture to the shredded chicken and stir to combine until the chicken is fully coated.
Top the dip with shredded mozzarella cheese and then bake at 400ºF for 15-20 minutes or until it begins to bubble. Option to broil the dip for a few minutes to brown the cheese.
Once the dip is hot, remove it from the oven. Sprinkle on blue cheese and diced green onion.
Serve with your favorite crackers, crostini, celery, carrots, or cucumber.
