I didn't see this on the opening page , so I hope this hasn't been discussed before

I'm off work today, recovering from the Flu and decided to watch Empire for the first time in about a year or so, and re-noticed a minor little something thats bugged me for a while. In the scene where Yoda meets Luke, Yoda grabs some sort of weird chocolate bar from Lukes rations, takes a bite and chews, yet the food remains completely intact, it always reminded me of the scenes on Sesame street whenever the characters mimed eating something. Is there any way to actually make it look he actually took a bite out of the bar?

It sounds like a minor thing, and I'm sure it's well within the realms of Ady's capabilities, but It would add more believability to Yoda in that brief little scene.
