If you have a sushi bamboo mat use it. Alternatively, spread a sheet of plastic wrap on your chopping board vertically. Lay the nori sheet on the prepared surface with the shiny side down and the lines on the nori running horizontal. Spread half the pâté evenly over 2/3 of a nori sheet, leaving an inch on the end closest to you. Spread the pâté all the way out to the side edges. Arrange cucumber, avocado, and red bell pepper on top of the pâté at the end closest to you, bringing the vegetables all the way to the side edges. Take a hold of the plastic wrap and bring up the edge of the nori to start rolling. When you have completed the first roll and covered the veggies, give a light squeeze on the wrap to secure the roll. Lift the edge of the plastic wrap and continue to use the plastic wrap to finish rolling, applying a little pressure for a tight roll. Roll until ½-inch of nori is left exposed, then lightly wet your finger and run it across the exposed nori. Continue rolling and lightly squeeze to seal and shape roll using the plastic wrap. Remove the plastic wrap and place the roll on the chopping board seam side down. Cut in half with a sharp or serrated knife. Repeat directions to make a second. Roll. Serve with the dip.
