Yes, you can mix entire meals into one drink. I think it's gross, but to each his own. My brother broke his jaw years ago. They removed a tooth, wired his jaw shut. He couldn't eat any solid food. Im sure this isn't your diet plan, but I would go to McDonalds for him, buy a big mac meal, bring it home and put it all in a blender with some chicken broth. Blend it until it was liquid so he could drink the entire meal through a straw. Funny thing is, he said it tasted just like a big mac meal.
