Edible Buffy

Faith: God, I could eat a horse! Isn't it crazy how slayin' just always makes you hungry and horny?
Buffy: Well... sometimes I-I crave a non fat yogurt afterwards.'
      Faith, Hope & Trick

I don't think anyone on the show actually ate a horse, but some things aren't that far off...

There also seems to be a recurring thing about cheese...
Willow: She likes cheese.
Riley: What?
Willow: Well, I'm not saying it's the key to her heart, but Buffy... she likes cheese.

Riley: Did i tell you I like cheese?

Cheese Guy: I've made a little space for the cheese slices.

Cheese Guy: I wear the cheese. it does not wear me.
