Press the Tofu: Begin by draining the tofu. Press it between two kitchen towels or paper towels with a heavy object on top to remove excess water. This step ensures that the tofu will absorb the marinade effectively. Slice the tofu into 1/2-inch thick steaks.
Make the Glaze: Mix miso paste, tamari sauce, mirin, grated ginger, minced garlic, and sesame oil in a bowl.
Marinate the Tofu: Cut the tofu into steaks and marinate in the glaze for at least 10-20 minutes.
Grill the Tofu: Heat a grill pan over medium heat. Grill the tofu steaks for 3-4 minutes on each side until nicely charred.
