Preheat oven to 350 degrees.
Prepare peppers by cutting the top 1 inch off and removing seeds and white ribs. Make sure to leave the top intact as that will be your "lid". Set tops aside and place bottom of peppers in a glass baking dish.
In a large bowl, combine turkey, cilantro, green onions, cumin, chili powder and sea salt. (Leave out green chiles unless you want all the pepper to be spicy)
Mix by hand and portion into bell pepper cups.
Portion out as many bell pepper cups as you want to be mild, then add the chopped green chiles to the turkey mixture and fill the rest of the peppers.
Place tops of peppers on to close.
Bake for 1 hour, then serve.
