Healthy shake on the go?

Originally I bought my Dad the Chocolate Shakeology which he did like, but always complained how he doesn't have enough time to make them. I know, it takes only 2 minutes, but that's the excuse he gave me, so I was thinking if there's a shake I could buy for him that's already put together and all he has to do is grab it and go.

Is there such a thing? If so, what do you recommend?
