Yuck, meat in a vat?
How about if whole humans are produced in manufacturing labs, but the DNA is altered that the human's brain is underdeveloped and only supports basic life functions - like a 'vegetable'. The rest of the physical traits can be adjusted via DNA selection to produce a cute, sexy girl or guy, sold to the public as a life sex toy. I'm sure the technology will be advanced enough to produce a young/adult human rather than a baby - the Mini-me problem. When you grow tired of her, you can even sell her to Jophiel's meat market.
Oh, you could also make a special order to clone yourself (minus the brain of course), just so you can go fock yourself.
