Yes, you can freeze shrimp egg roll in a bowl. After cooking and allowing it to cool, transfer the leftovers to an airtight container or freezer-safe bag. Make sure to remove any excess air to prevent freezer burn. Label the container with the date and store it in the freezer. When ready to enjoy, thaw the frozen shrimp egg roll in a bowl in the refrigerator overnight and reheat it in a pan or in the Ninja Foodi. Note: The texture of the vegetables may be slightly softer after freezing and thawing, but the flavors will still be delicious. You may also find it to be more liquid. Simply drain off the excess liquid and add a little more seasonings, if needed.
