Squeeze the lemon juice
over the avocado to prevent browning.
Cover a bamboo rolling mat with plastic wrap
. Cut nori sheets in half crosswise. Lay 1 sheet of nori
, shiny side down, on the plastic covered mat. Wet your fingers with water and spread about 1/2 cup of the rice evenly onto the nori. Sprinkle the rice with sesame seeds. Turn the sheet of nori over so that the rice side is down. Place 1/8 of the cucumber
sticks in the center of the sheet. Grab the edge of the mat closest to you, keeping the fillings in place with your fingers, and roll it into a tight cylinder, using the mat to shape the cylinder. Pull away the mat and set aside. Cover with a damp cloth. Repeat until all of the rice has been used. Cut each roll into 6 pieces. Serve with pickled ginger, wasabi
and soy sauce
