In a small bowl, stir together the soy sauce, toasted sesame oil, brown sugar, and sesame seeds.
Drain the tuna well, then add it to a bowl.
Dice the red bell pepper (I served the other half on the side with the tuna salad) and slice the green onions.
Add the bell pepper and green onion to the bowl with the tuna.
Carefully fold the ingredients together until everything is coated in dressing.
Serve immediately, or refrigerate until ready to eat.
