Eggs would definitely be one food -they are versatile and can be cooked several ways -and possibly bacon as the other....hard to pick between bacon and Nestles Sweetened Condensed milk which I also adore!
This is SUCH a hard one to answer correctly,so I shall do a small cheat and say 'Fruit' meaning ALL sorts of fruit!!! And cheese as this also has many varieties ,and they go so well with the fruit!!! Yummmm.....!!!!
Two foods forever, I'm not one who requires a lot of variety but thta may be quite a challenge. Perhaps bread and vegemite. Bread because it's a staple and vegemite becuase I live it and its moist enough to make the bread better. In fact I'll make and Aussie choice and say bread and OzEmite (Dick Smith's all Australian alternative.)
