Most supermarkets have a Gf section and I buy muesli bars etc from there. I use GF gravy/sauces/stocks to put in meals. You can get rice flakes or rice crumbs to use instead of normal bread crumbs.
Almost any recipe can be made gluten free if you substitute flour for gluten free flour or baking mix but it helps to add guar gum to most recipes as it acts as a gluten subsitute (holds everything together).
Tell your SIL to look up the allergy nz (Or Aus) website and have a look. and if she can get hold of their cookbook it's wonderful, has recipes for everything in it. Make sure she reads labels on things, I was surprised how many items gluten is in and sometimes companies change their ingredients. Hope that helps! If you have any questions just ask!
