Heat oven to 400°F (200°C).
Beat the eggs, egg whites and milk, then set aside.
Heat the coconut oil in a pan over medium heat. Add the onion and cook for 3 minutes until softened and browned.
Add in the turkey, oregano and cumin, season with salt and pepper. Cook until meat is cooked through, about 5 minutes. Then add the spinach, and mix until it wilts about 2 minutes.
Increase the heat and add in the eggs. Pull the eggs across the skillet with a spatula. Repeat for about 3 minutes until eggs are cooked. Then set aside.
Cut the peppers horizontally and remove the seeds, then stuff with the scrambled eggs and turkey.
Place the peppers in a baking dish and sprinkle them with grated cheese.
Bake in the oven for 15 minutes, until cheese has melted and the edges have browned.
To serve, sprinkle with chopped parsley.
