How to Make It
In a small, heatproof bowl, combine the lemongrass with the ginger, cilantro, mint, sesame seeds, scallion, garlic, crushed red pepper, soy sauce and rice vinegar.
In a small saucepan, heat the oil over high heat until almost smoking, about 2 minutes. Meanwhile, arrange the tofu slices on a plate. When the oil is hot, pour it over the lemongrass mixture; it will sizzle. Immediately spoon the hot ginger-lemongrass sauce over the tofu and serve.
