Cook the Sushi Rice: In a small saucepan, combine the rinsed sushi rice and ½ cup / 120ml (4.1 fl oz) of water.
Bring to a boil, then cover, reduce the heat to low, and simmer for 20 minutes, or until all the water is absorbed.
Remove from the heat and let it cool for 20 minutes before gently stirring in the seasoned rice vinegar.
Assemble the Roll: Place one sheet of nori, shiny side down, on a sushi mat or clean work surface. With damp fingers, spread half of the seasoned rice evenly over the nori, leaving a 1½-inch border at the top.
Sprinkle the rice with hot sesame oil, if using.
Add Fillings and Roll: Arrange 2 avocado slices, 2 bell pepper slices, and 4 tofu strips in a line across the center of the rice.
Top with 1 Tbs of pickled ginger and ¼ cup of broccoli sprouts. Lightly brush the top border of the nori with water. Tightly roll the nori up and over the filling, pressing gently to seal the edge.
Slice and Serve: Using a very sharp, wet knife, slice the roll into 8 equal pieces.
Repeat the process with the remaining to make a second roll.
Serve immediately with soy sauce and wasabi.
