Preheat your oven to 300°F and line a small baking dish with parchment paper for easy cleanup.
In a small ramekin, whisk together the smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Pat the pork ribs dry with a paper towel, then coat them evenly with the olive oil.
Sprinkle the dry spice rub over all sides of the pork, pressing it in firmly so it adheres to the meat.
Place the ribs in the prepared dish and cover tightly with foil to lock in the moisture during the slow cook.
Bake for 90 minutes, or until the pork is tender and easily pierced with a fork.
Carefully remove the foil, drizzle the apple cider vinegar over the ribs, and broil on high for 2 to 3 minutes until the edges are slightly charred.
While the ribs rest for a few minutes, steam the fresh green beans for 5 to 6 minutes until they are bright green and have a slight snap.
Plate the smoky ribs alongside the steamed green beans and serve immediately.
