If there's one thing Dr. Tygan misses more than his lab equipment, it's those damn tasty ADVENT burgers.
There have been several references that the food the ADVENT administration serves is of dubious origin. Tygan doesn't want to know what their burgers are made of, it sounds like cows have gone the way of the dinosaur, and food seems to just "appear" from ADVENT facilities. Do we actually know what ingredients go into an ADVENT burger, or is it just a running gag?
