To prepare tofu, whisk Sesame Oil, Mirin, Lime Juice, Sriracha, Tamari, Black Pepper, Garlic, Ginger and Lemongrass in a bowl till well combined. Pour over sliced tofu and make sure to coat all your tofu with this mixture. Cover tofu in plastic wrap and refrigerate overnight.
To make picked vegetables, combine Carrot, Cucumber and Jalapeno in a jar. In a bowl, whisk Rice Vinegar, Water, Sugar and Salt till dissolved. Pour mixture over the vegetables in the jar and make sure all the vegetables are covered in this pickling liquid.
Cover jar with a lid and leave in the refrigerator overnight.
On the next day, heat a frying pan up and sear tofu on high heat. Cook until tofu is charred on both sides. It will splutter!
To assemble, make a pocket in each Baguette slice and slather liberally with Vegan Mayonnaise. Fill with seared tofu, picked vegetables, fresh cilantro and drizzle with Sriracha.
