In a large pot cook the bacon, add the avocado oil if needed, add the onions and cook until tender.
Add garlic and red pepper flakes and cook until garlic is fragrant.
Add everything except the collard greens and bring to a boil.
Turn the heat to a simmer, cover, and simmer for 45 minutes, this gives the smoked turkey time to cook and soften. I only cook my collard green for 45 minutes, if you prefer a more cooked collard green then you can add them now.
After 45 minutes add the greens and simmer for 45 minutes.
About 10 minutes before this time is up remove the smoked turkey and let it cool, so you can remove it from the bone, chop it up and return it to the greens.
Once the time is up, add the smoked turkey back and add kosher salt about 1 tsp. Taste and add more salt if needed.
Serve with vinegar and hot sauce at the table.
