In a small bowl, whisk together the marinade ingredients and set aside
Place the sliced tofu in an appropriately sized dish for marinating and pour the marinade over the tofu, making sure to cover all of the pieces.
Place the marinating tofu in the fridge for at least 30 minutes to 1 hour.
When the tofu is almost finished marinating, preheat your grill so that it's warmed. Use tongs to transfer the tofu from the container to the grill, making sure they're evenly spaced.
Use a basting brush to top each of the tofu pieces with the leftover marinade from the container.
Cook the tofu at around 350°-400° for about 8-10 minutes on each side. Apply more of the marinade as desired.
Once finished, remove from the grill and garnish with sesame seeds and green onion (optional). Enjoy!
