Steam the cauliflower rice and broccoli just until tender. Avoid overcooking, as excess moisture can make the casserole watery.
Fry the bacon until crispy, then crumble it once cooled. Make sure your chicken is already cooked and shredded before mixing.
In a large bowl, combine the vegetables, shredded chicken, bacon, cheese (reserve some for topping), eggs, and seasonings. Stir well until evenly mixed.
Transfer the mixture into a greased baking dish. Sprinkle the remaining cheese on top and bake at 350°F until bubbly and lightly golden.
Let the casserole rest for a few minutes after baking. This helps it set and makes serving much easier.
