Place neck bones (or innards) in a covered medium size boiling pot of water. Occasionally check them and add more water as needed. Neckbones should always be submerged in water. Let them boil for 45-60 minutes or until meat is tender and falling off the bones. Remove them from the pot and let cool. Reserve stock.
Use fork and/or hands to remove shredded meat from bone (and or chop) and set aside.
Preheat oven 350 F
Add oil to medium sized pan on medium heat. Once hot add onions, celery and bell peppers and cook for 5 minutes. Add mushrooms and cook until all vegetables are softened. Add in all seasonings: sage, oregano, thyme, granulated garlic, onion powder, salt and pepper as well as the shredded meat and mix together. Then remove from heat.
