Once the rice and vegetables are done cooking (or during if you're able to!), make the crispy tofu.
Remove the extra-firm tofu from it's packaging and slice it in half vertically. Lightly press each half between paper towels to remove excess moisture. For this recipe it's okay if the tofu is moist, but you don't want it to be soaking wet.
Then, add the cornstarch, nutritional yeast, and the remaining half of the seasoning mix to a large bowl.
Cut the tofu into cubes and pour them into the bowl of dry batter. Mix until coated.
Heat the oil in a non-stick pan. Once it has warmed for about 1 minute, add in the dry coated tofu slices.
Pan-fry the tofu slices for about 3-5 minutes on each side until crispy and browned (about 12-15 minutes total).
Once crispy, remove the tofu from the pan and set aside.
