Preheat your oven to 300°F and line a rimmed baking sheet with parchment paper.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Rub the spice mixture thoroughly onto both sides of the pork ribs, pressing it into the meat.
Wrap the ribs tightly in a large piece of aluminum foil and place them on the baking sheet; roast for 2 hours until the meat is very tender.
While the ribs roast, whisk together the tomato paste, 1 tablespoon of apple cider vinegar, honey, and liquid smoke in a small saucepan over low heat until thickened.
In a separate medium bowl, toss the shredded cabbage and carrots with the olive oil and the remaining teaspoon of apple cider vinegar.
Carefully unwrap the ribs, brush them generously with the prepared BBQ glaze, and broil for 3-5 minutes until the glaze is bubbly and slightly caramelized.
Slice the ribs between the bones and serve immediately alongside the crisp vinegar slaw.
