Make sure your cornbread and bread cubes are dried completely. Chop the onion, celery, and peppers into ½" dice.
Turn the Ninja Foodi (see other cooking methods in recipe notes) on high sear/sauté and add the butter and sausage. Break the sausage up into bite size pieces. Add the diced vegetables and cook for 3-5 minutes.
When the pot is sizzling, add the seasoning blend, stir and continue cooking for another 3-5 minutes or until the vegetables are soft and the sausage is cooked through.
Add the dried cornbread, maple syrup, and ½ cup chicken broth and fold until the cornbread reduces in volume and absorbs the liquid.
Add the bread cubes and remaining chicken broth. Fold until the white bread absorbs the liquid and softens. If after folding and sitting for a minute, the bread still looks dry, add a bit more chicken broth.
Close the crisping lid and select bake/roast on 350℉/175℃ and the time for 30 minutes. Bake for 8-10 minutes and fold the mixture a few times and bake another 8-10 minutes. This allows the browned top to go into the dressing and expose the softer parts to the heat. This is completely optional though. If you Don't want crispy parts in your stuffing, you can stop now. Repeat until the stuffing is done to your liking. I usually bake for 25-30 minutes folding 3 times.
** Don't use cornbread with whole kernels of corn or the corn becomes very hard and unpleasant when the cornbread dries.
