My cat Archie just loves Broccoli, he'll do anything for it. He turns his nose up at meat and fish in favour of the broccoli. I even have to keep an eye on him when I cook it as he has, on more than one occassion blistered his paws by standing on the hob trying to get the broccoli out the pan.
Actually he also has a horrible habit of trying to dive into the (tiny) tub of honey and walnut youghurt when I open it, he gets all very excited - its the only flavour he is remotely interested in and I used to find it quite cute but unfortunately I've ended up wearing the youghurt too many times to still find it quite so cute
