Heat the peanut oil in a small skillet over medium heat. When hot, add the pine nuts and garlic and cook, stirring, until lightly browned, 3 to 4 minutes. Transfer to a medium bowl to cool. Add the onion, cilantro, mint, sesame oil, and cinnamon to the bowl and stir to blend. Rub this mixture all over the pork loin. Roll the pork loin into a cylinder, tying in places with kitchen twine to keep it closed and uniform. Season with salt and white pepper; wrap the bacon slices around the meat.
