Preheat oven to 250°. Combine 2 tablespoons salt, brown sugar, and next 9 ingredients in a blender; process until smooth. Rub pork with canola oil; sprinkle with black pepper and remaining 1 teaspoon salt. Place pork on a rack coated with cooking spray set inside a jelly-roll pan. Brush pork evenly with jerk sauce mixture. Cook 4 to 4 1/2 hours or until pork is fork-tender, basting with additional sauce every 30 minutes. Transfer pork to a plate, and cover loosely with aluminum foil. Let stand 15 minutes.
Place 1 pork belly portion on each of 6 plates; top each serving with 1 Quail Egg. Serve with Red Slaw and Fava Beans.
