Turn leftovers into Asian-inspired pulled-pork sandwiches.
Stir together shallots, fish sauce, 1/4 cup honey, 1 1/2 teaspoons salt, and 1/2 teaspoon pepper in a 5-to-6-quart slow cooker. Add spareribs; toss to coat. Cover and cook on low 7 hours.
Preheat oven to broil, with rack 4 inches from element. Transfer ribs to a rimmed baking sheet, meat-side up. Broil until browned, 4 minutes. Pour juices from slow cooker through a fine-mesh sieve into a small saucepan; discard solids. Bring to a boil, then cook until syrupy, 5 to 10 minutes. Brush some glaze onto ribs.
Combine carrots, cabbage, lime juice, mint, oil, and remaining 2 teaspoons honey. Season with salt and pepper. Serve ribs, with slaw and remaining glaze alongside.
