Put the diced mushrooms, crushed garlic and sesame oil into a small frying pan and saute until just softened
Stir in the vegetable stock and remove from the heat
Tip the mushroom mixture into a food processor bowl along with the tofu, nori, tahini, salt and lemon juice and whizz everything to a smooth paste
Divide evenly amongst the 6 slices of bread, spreading thickly on each one
Cut the bread slices into 4 triangles
Put the sesame seeds onto a plate or shallow dish and push each triangle into the sesame seeds. Push quite firmly so the seeds stick well into the paste
Heat a good drizzle of oil in a large frying pan and lay in several of the bread triangles, sesame seed side down
Fry for a few minutes, carefully checking occasionally to see if the sesame seeds are turning golden
Once they're gently coloured carefully turn the toasts over and fry for a couple of minutes on the other side
Drain the prawn toasts on kitchen paper
Repeat with the remaining triangles (see note)
Notes
These prawn toasts are best served within a couple of minutes of frying for best crispness but can be kept warm in the oven while you fry the rest of the batch
