Preheat the oven to 350° F.

Whisk together the 12 eggs in a large bowl. Shred the turkey and dice the carrots, green onions, bell pepper, and mushrooms. Add turkey, carrots, green onions, bell pepper, mushrooms, parsley, cheese, salt, and pepper to the eggs. Mix well.

Scoop stuffing into a greased square baking pan. Press it down with a spoon to form an even crust layer. Pour the egg mixture evenly over the stuffing crust. Bake for 45 minutes. Let it cool for 5–10 minutes, slice into squares, and serve warm. Enjoy!
