My book is set in the future - a world having recovered from a major bacterial disaster. The survivors have clung to city life , but their produce is low ( only the rich can afford actual vegetables , and cuts of meat ) because space is also an issue they've turned to a lot synthetic food. I want to sound authentic but I don't want to sound like I'm ripping off Soylent Green minus the cannibalism. Any ideas? So far I've rattled around chemical based drinks ( jeepers, now I sound like Logan's Run ) , pills to balance out their nutrition , and a legume based bar ( sort of like a fruit bar ) spiced up with meat drippings.
