the pots and pans, complete with cutlery and utensils can be picked up from Argos for about £25 as a 'get you started' job lot. Great gift if you know someone that suddenly got landed on their own!
They will wear out and break after a while, but will at least get you on your way.
Anything else can be picked up along the way. I'd recommend getting wooden utensils fairly soon though.
The plastic trays that you're takeaway fried rice comes in? Yeah, keep them dont bin them. Nah, nothing to do with saving the environment... these are going to come in handy!
