Preheat your oven to 300°F and line a baking sheet with foil.
Remove the thin membrane from the back of the ribs to ensure the spices penetrate the meat.
In a small bowl, mix the smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Rub the spice blend thoroughly over all sides of the pork ribs.
Wrap the ribs tightly in aluminum foil and bake for 2.5 to 3 hours until meat is tender and pulling away from the bone.
Carefully open the foil, brush the top of the ribs with the sugar-free BBQ sauce, and broil for 3-5 minutes until caramelized.
While the ribs rest, steam the green beans until bright green and crisp-tender, then toss with apple cider vinegar.
Slice the ribs between the bones and serve immediately alongside the tangy green beans.
