We have synthetic burgers (grown from stem cells), entire fish farms cultured from inedible waste concoctions, nutrient rich 3D printed tablets and ornate toy-like cartridges for seniors and space men alike, microalgae breads and snack wafers, tofu anything, meat substitute protein packs made from bacteria, and sushi made from practically anything, and skinned meal balls (that look like large testicles) though only different ice creams at the moment. That's just what I see as being close to dystopian theme.. but cyberpunk could really take in coca-cola and Pepsi and the endless soda wars, the large mass chains like McDonalds, or the ones who have merged to survive like Taco Bell and KFC.. any product marketed under false pre-tenses like a fair chunk of the current gluten-free market that trades gluten for arsenic, and well all the synthetic sugar substitutes out there.
But I doubt any of this would stand out all that much if you were planning a cyberpunk themed meal unless you wanted to make a steak out of spam. ;)
