When I was in my teens, though, they had these soy “hamburgers” at the drive-in theater snack bar that had some flavoring, that I LOVED. Could only get them at the drive-in.
Ours were just flavored like soy. Absolutely disgusting. I wouldn’t doubt that you were supposed to flavor them and the lunchroom ladies were either too lazy to do it, or didn’t know to do so.
I remember one school I attended that had the most delicious little hamburgers, fries, and tacos. Man I loved them. 25 years ago and I can still almost taste them. There was something really special about them, I’d kill to have them again.
