Slice the tofu into ½-inch thick pieces (squares or rectangles - about 2x2 or 2x3). You should get between 6-8 pieces, depending on the tofu you choose. Arrange the tofu in a shallow dish (about 8X8).
Now prepare the marinade in a small bowl. Whisk together the tamari, rice vinegar, sesame oil, and minced garlic. Pour the marinade on the tofu and allow it to marinate for 30-60 minutes in the fridge. Flip midway through.
While the tofu is marinating, prepare the dipping sauce. Combine the lime juice, tamari, maple syrup, garlic, and red chili flakes. Whisk well to combine. Now add the green onion and gently whisk to combine. Set in the fridge. Taste and adjust flavors after it has marinated for a bit. You can add more sweetener, lime juice or tamari if it needs balancing.
When the tofu is almost done marinating, prepare the breading station. In a shallow bowl, combine corn starch, salt & pepper. In a second shallow bowl, place the aquafaba. In a third shallow bowl, combine panko bread crumbs and sesame seeds.
Pick up one piece of tofu out of the marinade, gently shake off any excess liquid, and press it into the cornstarch to coat lightly. Gently shake off excess. Now, dip it into the aquafaba and let the excess drop off. Now press the tofu into the panko breadcrumbs & sesame seeds. Press gently on all sides to coat well. Place the coated tofu piece on a plate and repeat the process until all pieces are coated. *Discard marinade.
Heat oil in a large pan over medium heat. Once the oil is hot and shimmering, carefully place the tofu in the pan, leaving a few inches in between each piece (work in batches if needed). Cook for 2-3 minutes on each side until the breading is crispy and golden brown.
Place the tofu pieces on a paper-towel-lined plate to absorb excess moisture. Garnish the tofu with spring onions and serve with steamed rice and dipping sauce if desired. Enjoy
