In another large ovenproof skillet over medium-high heat, brown the pork in the butter. Transfer to the oven and bake for 30 to 35 minutes or until a thermometer inserted in the centre of the roast reads 135°F (57°C). Set the pork aside on a plate, keeping the cooking fat in the skillet. Let the pork rest until the thermometer reads 145°F (63°C). On a work surface, slice the pork between the bones.
In the same skillet over medium heat, lightly brown the garlic in the pork cooking fat. Add the lettuce and cook until just wilted. Season with salt and pepper.
Divide the lettuce, pork and onion halves among four plates. Sprinkle with the spelt crumble. Serve with the cider sauce.
