Earlier quoted context omitted.
Almost all foods seem to get destroyed in the freezing process and lose their texture. I have found that at my supermarket they sell refrigerated meals that just need to be microwaved and they taste outstanding. As long as you make sure to stir them half way through so they don't dry out at the top you could literally serve it at a restaurant and I don't think people would notice.
I have a feeling there are more than a few restaurants which do basically exactly this.
This is a major supplier.
