Place all of the pesto ingredients into a powerful blender or food processor and blend until a smooth pesto forms.

In a bowl, mix together the cumin, chilli powder, 2 tablespoons of olive oil and a large pinch of salt. Mix well.

Drain the tofu and pat dry with some kitchen roll, then cut the tofu into slices before placing into the bowl with the spiced oil. Mix well until all of the tofu is covered in the oil mixture.

Place a large pan over a medium-high heat and add a drizzle of olive oil.

Once hot, add the tofu to the pan and cook for 5 minutes until the side facing down is crispy.

Flip the tofu over and cook on the other side for 3-5 minutes until crispy.

Once both sides are cooked, remove from the heat and leave to cool a little on some kitchen roll.

Toast the bread and spoon some pesto onto one slice.

Top with the crispy tofu, some salad leaves, a sprinkle of chilli flakes and sandwich together with the last slice of toasted bread.
