Take the sushi mat and place a plastic wrap over it.
Next, add brown rice or cooked sushi rice.
Now, another plastic wrap is to be laid over the top.
Use a rolling pin to roll out the wrap until a rectangle is formed, which could accommodate nori wrap over it. It should be ½ inch thick.
Now, take away the wrap from the top. With the shiny side facing up, lay nori wrap over the top.
Next, place the imitation crab meat, avocado, cucumber, mayo, and oyster sauce over it.
Pull up the sides of the underlying plastic wrap in order to keep the rolls closer.
The rolls are to be pressed into a long cylinder.
Top the rolls with mayo, oyster, and French fried onions.
Cut the rolls using a sharp knife. In order to prevent them from sticking, dip the knife in rice vinegar or water.
