well the pans i use the most are:
a large pan for the potatoes, after peeling and chopping it takes the right amount for sunday roasties or enough to make the mash topping for shepherds pie,
the next size down pan for pasta and rice,
a pan for jam/marmalade which i found in a charity shop,
a red wok (sort of a pan

) again i found in a charity shop and is so handy for stir fries, browning and pancake making and replaces the one i left behind when i moved,
OHs omlette pan,
a big stew pot which was marked half price and i also had a voucher for £5 so price £20, its great for stews and soups,
and i have a 2 tier steamer which is great for the veg.
and the pans favoured by the teens - the baked bean pan (the contents of one tin fits in it) and the noddle pan (just right for instant noddles) also good for scrambled eggs! and not forgetting my favourite is a little green enamel pan which i heat my tomato soup in,
space is tight so they're either stacked inside one another in the pan cupboard (abit obvious

) or on top of the cupboards which i can just reach (having teens taller than me is a bonus when it comes to getting that pan down without hitting myself on the head...ouch

)
