Place one sheet of seaweed on a bamboo sushi mat.
Spread a thin layer of rice on the seaweed sheet, leaving a 1 inch gap on the top.
Neatly arrange red cabbage, carrot, radish, cucumber, egg and bulgogi beef across the center of the rice.
Roll the bamboo mat up, curling the seaweed and rice around the fillings, then roll all the way up. Then gently squeeze the roll so it holds its shape. Set roll aside and repeat with the remaining ingredients.
When you finish assembling the rolls, brush them with sesame oil, then cut into bite sized pieces. Garnish with sesame seeds and serve. Enjoy!
