Cut the tofu block into 1/2″ thick slices and with towel, pat each slice tofu dry on both sides.
In a small bowl, add just 1/2 of the miso (we’ll use the other half in the dressing). Brush the tofu on one side with some of the miso.
Heat a frying pan over medium-high heat. When hot, drizzle in the cooking oil and add the tofu, miso side down. Cook for 2-3 minutes until browned. Brush the top of the tofu with more miso. Carefully flip the tofu and cook for 2-3 minutes.
