Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper.
Pat the baby back ribs dry with a paper towel and rub both sides with avocado oil.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Apply the spice rub evenly over the ribs, pressing it into the meat.
Wrap the ribs tightly in a double layer of aluminum foil and place on the baking sheet.
Bake for 2 hours or until the meat is tender and starting to pull away from the bone.
Remove from the oven, carefully open the foil, and brush the ribs generously with the sugar-free BBQ sauce.
Set the oven to broil and place the ribs back in for 3-5 minutes until the glaze is bubbling and slightly charred.
While the ribs rest, steam the green beans for 5 minutes until crisp-tender, then toss with apple cider vinegar.
Slice the ribs between the bones and serve immediately with the bright green beans.
