Put leftovers in an airtight container with as much of the juice as it will hold. Store in the fridge for up to 3-4 days. You can also freeze pulled pork. Just make sure you add the leftover liquid from the crock in the freezer bag. This helps the meat from getting freezer burn. For a meal prep option, you could divide the leftovers into smaller portions before freezing. Then you can pull out of the freezer just the amount you need.
