Lay a tortilla bread on a plate and cover one side with chocolate spread.
Sprinkle on some plain or sweetened nuts, I recommend pistachios or caschews, and fold in half.
Place a small knob of butter in a frying pan and pop in your tortilla. Leave to cook for a minute or so.
Flip over and cook for another minute. Place on a plate and cut in to triangles. Serve hot and sprinkle with icing sugar.
