Start by cutting the carrot and cucumbers into a very narrow stick pieces of even length. Cut the salmon and avocado into pieces. Around 20 pieces each. Arrange a row of seaweed sheets into a cutting board. While wetting your hands with cold water, wet the short edge of each sheet. Proceed to add one piece of each ingredient. Salmon (could be used as topping or inside roll), cucumber, cream cheese, avocado, and carrots. Repeat this step for the entire roll of seaweed. To finalize, roll and press edge to seal. Cut piece in smaller bite size pieces and top with scallions and smoked salmon to your liking. Enjoy!
