Preheat oven to 350 degrees f.
Slice peppers in half lengthwise. Remove seeds.
I place them in a large pot of boiling water for 3 minutes, then drain very well. Just to make them easier for kids to eat.
Place peppers, evenly in a glass baking dish. Set aside.
Sauté onions with the oil for 2-3 minutes, then add the turkey in a skillet and cook until just browned.
Add the seasoning, and corn (if using) and continue cooking until the meat is just cooked.
Drain. Add salsa. Stir.
