Prep the tofu: Cut the firm tofu into rectangular pieces that are easy to wrap. Pat each piece dry gently with paper towels so the surface isn’t wet. Tip: drier tofu = crispier finish.
Cut the nori: Cut nori sheets into long, even strips (keep the width consistent, about 1.5 inches, so the rolls look neat).
Wrap the tofu: Wrap a nori strip around each tofu piece. Give the wrapped pieces a quick pat to settle the nori against the tofu.
Dust with cornstarch: Lightly coat each nori-wrapped tofu piece in cornstarch. This helps build a golden crust and gives the sauce something to cling to.
Pan-fry until golden: Heat oil in a pan over medium heat and fry the tofu, turning gently so each side gets golden and crisp (about 3 minutes per side). Be careful when flipping so the nori stays snug.
Mix the teriyaki sauce: While the tofu is frying, whisk your sauce ingredients together in a bowl until everything is combined.
Add the sauce and toss: Pour the sauce into the pan and toss the tofu gently so each piece gets coated. Let the sauce bubble and reduce until it becomes glossy and starts to cling to the tofu, about 1 minute on medium low heat.
Finish and serve: Once the sauce is thick and shiny, remove from heat. Serve the tofu over rice or in a bowl, and sprinkle with sliced green onions and sesame seeds.
