Whole wheat sandwich with crunchy tofu, guacamole and spinach

Cut the tofu into thin slices and marinate with spices to taste and a dash of oil and lemon juice. Leave to marinate while preparing the bread. Place the tofu in the pan with its marinade and cook until it changes color and becomes crispy.

Toast the bread to taste (you can use any good processed variety).

Spread the guacamole on the tostadas, add the tofu and spinach on top.
