First, Make the marinade by combining soy sauce, olive oil, vinegar, miso paste, herbs, paprika nori flakes and water in a container. Cut the tofu into triangles and place it in the container. Shake to coat and then leave for at least 30 minutes, the more the better.
Place the tofu on baking sheet with baking paper and top it tofu with nori sheets in the same shape of the tofu. Bake it in the oven for 25 minutes at 180C (static).
In the meantime cook some potatoes cut into cubes in boiling water until mashed and do the same with frozen spinach. Drain and season with extra virgin olive oil or vegan butter, salt and pepper. Serve the tofu on top of roughly mashed potatoes and spinach, and add some toasted breadcrumbs. You can add some more of the marinade liquid on top too.
