How much meat was in a Legionary\'s diet?

[Magnus]

I have no doubt that they DID eat meat...I was more wondering about the frequency. Us modern folk (In N. America) eat waaaay too much, almost with every meal. I am curious to see if there is any evidence as to what frequency the Romans had meat. I understand there were different circumstances that would have allowed them to acquire it, but was it always a greatly desired menu item all the time? Or more of an opportunity as it arose?
