Cut the tofu into fillets, and brush on 2 tablespoons of soy sauce on both sides. Allow to sit and marinate for about 10 minutes
Using a food processor or similar device, pulse the pistachios into fine crumbs. Place them in a bowl with the bread crumbs and pepper and mix.
In another shallow bowl add the 1/2 Tablespoon of soy sauce, hoisin sauce, and sriracha.
Dip the tofu fillets into the mixture, then into the bread crumb mixture, and place on a lightly oiled baking sheet. You may want to add more bread crumbs to the fillets by gently pushing it down on top.
Bake for about 20 minutes or until the bread crumbs turn golden brown. Serve with pasta or rice and add a bit of sauce to the top - i used hoisin.
