To make the stuffed rice rolls, wrap a paper towel or sushi mat with a layer of plastic wrap or wax paper.
Lay the wrapped mat or paper towel on a flat surface, then sprinkle with a pinch of sesame seeds.
Scoop about ¾ cup of rice and place onto the surface, on top of the sesame seeds.
Using a silicon or rice spatula, spread the rice to a thin layer by pressing the rice down into a rectangular shape.
Add a heaping spoon of tofu in the middle and top with youtiao.
Add a tablespoon of greens, cooked preserved radish, and purple cabbage. Top with a heaping spoon of crushed peanuts if preferred.
Now, lift both sides of the wrapper up and use your finger to push the filling onto the rice.
Bring the long sides to the middle and fold them in a hot dog style. Use the side of the wrapper to push both ends so the rice sticks together. (think of how you wrap a candy)
Then, twist both ends several times so the rice roll is packed like a log. Tip: Transfer roll to a wrap, tighten & keep it wrapped while cutting or serving.
Sprinkle with more toasted sesame seeds on the outer layer. Serve warm.
