Wash collard greens thoroughly then remove stems and chop the leaves. I recommend stacking the leaves on top of each others, cutting into four strips lengthwise, then cutting the strips into pieces.
Add olive oil to pot over medium heat. Meanwhile, dice the bell pepper and onion and mince or crush the garlic.
Add onion and bell pepper to heated oil, followed by onion powder, garlic powder, cayenne pepper, black pepper, and sea salt. Cook until mixture is fragrant and onions are just about translucent then add in garlic and cook for one more minute.
Add smoked turkey and stock or broth to pot then bring to a boil. Reduce heat to low and let simmer and bubble for about 20 minutes then remove turkey from the pot.
Add collard greens, apple cider vinegar, and brown sugar to the pot and stir to cover with the liquid.
Shred the meat from the turkey bones the stir into the pot. Collard greens should be starting to wilt at the point. Cover and reduce heat to medium low and simmer for up to one hour, depending on your desired texture.
Serve with hot sauce.
