I am looking for a manufactuerer that makes meal diet replacements under my own label?

Answer 1

Not much response to your question, so thought I'd scout the Internet even though it's not my area of expertise. Obviously the range of subcontractors available to you will depend on your anticipated production levels.
If you class your recipies as health foods then I guess there's a chance http://www.hfma.co.uk/ might be willing to put you in touch with some of it's members.

Answer 2

Not clear on what you're asking as your question is structured in such a way that it's not sensible.

Are you looking to begin marketing your own meat-replacement item and are wanting a manufacturer for the product?

Then you need to use the internet to research this process, or the public library for more information on the process.
