Combine tamari, rice vinegar, hoinsin sauce, grated ginger and chili flakes in a bowl.
Add the tofu blocks to the marinade and make sure it covered all parts of the tofu blocks.
Preheat a grill pan over medium heat with some sesame oil.
Preheat another nonstick pan over medium heat with some sesame oil.
Start by adding the bok choy to the nonstick pan and let it fry for 3-4 minutes, until it starts to get golden brown and a bit soft.
Add the two tofu steaks to the grill pan and let it fry for 2-3 minutes on each side. (Don't throw away the remaining tofu marinade, you will use it later)
When the bok choy is done add a little more sesame oil and fry the cauliflower rice in it and add the lime juice at the end. The cauliflower rice should be golden brown and a little softened, but not cooked thorugh. You still want it to hold some crunch.
Divide the caulifower rice between two plates.
Slice the tofu steak and place on top of the cauliflower rice. Add the remaining marinade on top of the tofu steak.
Place bok choy on the side and brush with more hoisin sauce.
Top with cilantro, sliced scallion and lime wedges on the side.
