Prep the tofu: Drain the tofu and wrap it in a clean kitchen towel.
Place a light weight on top and press for 15–20 minutes to remove excess water. Cut into 1/2-inch cubes.
Whisk the dressing: In a bowl, combine soy sauce, rice vinegar, mirin, citrus juice, sesame oil, ginger, garlic, sweetener, and spice. Taste and adjust salt, acid, and sweetness to your preference.
Marinate the tofu: Add diced tofu to the dressing and gently toss.
Let it sit for 15–30 minutes, stirring once or twice so every piece gets coated.
Prep the vegetables: Slice cucumbers thinly, julienne the carrot, and slice the bell pepper and scallions. Keep everything bite-sized and crisp.
Combine: In a large bowl, add the vegetables and herbs. Spoon in the tofu with a few tablespoons of the marinade.
Toss gently to avoid breaking the tofu.
Finish with texture: Sprinkle toasted sesame seeds and nori strips on top. Add a splash more marinade if needed, but don’t drown the vegetables.
Serve: Enjoy right away for maximum crunch, or chill for 10–15 minutes to let the flavors settle.
