I think it should actually be 'Comment trouvez-vous votre viande', whoch would mean 'how do you find your meat'. Seeing that the lady has quite a lot of it, I think it's quite easy to figure out the sense.
Isn't it more like "Comment voulez-vous votre viande?", which is closer to what was written here and means "How to do you want you meat?"...medium sounds good to me!
