If you have not allowed your bread to dry or become stale, heat the oven to 200 and cook the bread until lightly toasted and completed dried out.
Turn the oven to 375 degrees. In a large bowl or pan add he cornbread and break up with your hands, not to fine, leaving some larger pieces. Tear and crumble the bread and combine.
Heat a saucepan with chicken broth. In a large skillet melt the butter and add the onions, celery and the green onions. Sauté until the onions are translucent being careful not to burn. When done, pour into the cornbread mixture.
Add the poultry seasoning, fresh sage and a little salt and pepper. Add the chicken broth starting with two cups and continue to add until you reach your desired consistency. If you are using pan drippings add a ladle and check for salt and pepper. Add more salt and pepper if needed along with the poultry seasoning. I'm careful with salt because your drippings have salt along with the cornbread and the broth, so I just check and add as needed. Pour the dressing into a buttered casserole dish.
Place into oven and bake until golden brown checking after about 30 minutes. Cook time will be between 30 and 45 minutes. If you like scrape the browns sides and stir back into the dressing, as this just adds more flavor.
Enjoy! Happy Thanksgiving!
