Add 2 tbsp of olive oil ( or vegetable oil) into a medium sized pan. Turn the heat to medium, and add in the chopped onions and peppers. Cook the vegetables until they softened, then remove from the heat.
In a large bowl, or dish crumble the cornbread. Add in the onions, and peppers, and fold in.
Remove the turkey meat from the bones, and add it along with the cornbread and peppers. Now dice the gizzards/gibblets, and add them along with the other ingredients. Fold in.
Pour the broth, from the bake dish that you cooked the turkey necks and gizzards in, into the dressing mixture.
Add in two large eggs, and stir in.
Last but not least pour in 1/2 cup melted butter.
Mix until everything is well combined, then place the dressing into a well greased dish.
Smooth out the dressing, then cover it with foil.
Bake the dressing in the oven on 350 F for about 40 to 45 minutes.
Remove the dressing from of the oven, and let it sit for about 5 minutes before serving.
