Drain and press tofu. If you don't have a tofu press, place tofu in between a clean towel with a heavy object, like a cast iron skillet on top.
Slice tofu on its side into thirds, then lay flat and cut into four squares. You will end up with 12 tofu squares (this makes them easy to flip.)
Pour sesame oil into a hot pan. Add tofu and tamari. Cook both sides on medium heat until browned and slightly crispy.
Quinoa
Rinse quinoa thoroughly. Bring quinoa and water to a boil. Reduce to a simmer and cook until water is absorbed, about 15 minutes.
Heat brown rice vinegar, sugar, and tamari in a pan until the sugar dissolves. Pour over cooked quinoa, and mix thoroughly. Let cool.
Sweet Dipping Sauce
Mix dipping sauce ingredients until sugar dissolves. Heat in a pan if necessary (or if you get impatient waiting for sugar to dissolve).
Sushi Rolls
Lay a nori sheet out on a cutting board with the perforated lines going vertically (if your nori has perforated lines). Spread ½ cup quinoa on nori sheet, pressing quinoa into nori and leaving about ½" of the far side uncovered.
Slice tofu squares in half so that you have 24 rectangular strips.
Layer 4 tofu strips and 2 long red pepper slices on quinoa. Roll tightly away from you. Wet the uncovered edge so that the roll will stick. Slice on perforated lines with a serrated knife, or to the size of your liking. Repeat with the other rolls.
