Combination of two recipes from "Cookery the Australian Way". Makes a big lasagne or 2 small ones. Recipe freezes well for --1 month when cooked; can be stored longer if final lasagne layer and cheese sauce are not added. This can be easily translated to a vegetarian lasagne by leaving out the meat sauce (will only need --150g lasagne and half of cheese sauce), or by substituting a bean or lentil based mix.
