1.rice you can microwave in minutes.
2.family size foil take away type containers with lids (found cheap ones in supermarkets but just the tray bake style, not with paper (or any type) of lid.

I bought approx. 8inch squared foil dishes with lids from Asda, around £1.50 for 3. I used them to make cheesecake to take to a party.

Home Bargains, without a doubt.
