My favourite would be Shepherd's Pie. Love it.

For sweet I like apple crumble with ice cream or custard. Yum

I've been watching the series "Dexter" on TV lately and in some of the episodes, he has been searching for the perfect Key Lime Pie.
It looks nice and I think I might have a go at making one. One problem, no Key Limes in Perth. Will have to substitute.

and if your mouth isn't watering now, there is something wrong with you. LOL
