Adapted from a recipe in 'The Australian Women's Weekly's TAPAS antipasto mezze'. Chorizo sausage - surprisingly NOT in the Zaar Kitchen Dictionary - is a sausage of Spanish origin made from ground pork, garlic and chillies, so if you cannot get chorizo sausages that gives you the general idea: just substitute with a sausage you really like. The appeal of the dish is certainly going to be largely determined by your choice of sausage; and if you like a bit of heat in your food, either choose a spicy sausage or add something like red pepper flakes in step three. 680g? Well, 500g = 1lb; 750g = 11/2lb, and exact quantities are obviously not crucial here. 5mm? 3mm =1/8 inch and 6mm = 1/4 inch. Again, the exact size of the slices is not crucial, but be ready to decrease or increase your cooking time according to the thickness of your sausage slices. You can prepare this recipe to the end of step two earlier in the day (and have the additional ingredients ready) and complete step three just prior to serving.
