Your body demands things in response to what is lacking, and these demands are usually reactionary rather than geared towards long-term applications.

I remember on a number of occasions where I'd crave meat ravenously. I think it's because I wasn't eating enough protein in general, or maybe because I wasn't eating enough calories in total. I don't think it could be attributed to any form of protein specifically, whether it be plant or animal derived.

Cravings can also be psychological. We crave things we have enjoyed in the past. I've craved hamburgers and fries a number of times. I don't think there is anything in our evolutionary makeup that would suggest we are programmed to crave hamburgers and fries.
