Preheat your oven to 300°F (150°C).
Prepare the ribs by removing the thin silver skin membrane from the back of the rack using a paper towel for a firm grip.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, sea salt, and black pepper to create a dry rub.
Apply the spice rub generously to both sides of the ribs, pressing the seasoning into the meat.
Lay the ribs on a large sheet of heavy-duty aluminum foil, drizzle with apple cider vinegar, and seal the foil tightly to create a packet.
Place the packet on a baking sheet and roast for 2 hours, or until the meat is tender and begins to pull away from the bone.
Remove the ribs from the oven and carefully open the foil packet; brush the top of the ribs with the sugar-free BBQ sauce.
Switch the oven to the broil setting and place the ribs back inside for 3 to 5 minutes until the glaze is bubbly and slightly caramelized.
While the ribs rest for a few minutes, steam the fresh green beans for 5 minutes until they are bright green and tender-crisp.
Slice the ribs between the bones and serve immediately alongside the steamed green beans.
