An easy and cheesy casserole that is one of my family's favorites!
In a large bowl combine cooked, shredded chicken, softened cream cheese, and mayo. Stir until evenly mixed. Add cheese, corn, peppers, kosher salt, pepper, and season salt (save some peppers to put on top of the casserole if desired). Stir until evenly mixed.
Put the mixture into a casserole dish. In a small bowl mix the panko bread with the melted butter and then place on top of the chicken mixture (and reserved diced peppers if desired).
Bake in a 400 degree oven for 20-25 minutes.
