Yep! That’s the recipe!
I went to a small private HS. When I was in school there, they didn’t want to deal with the insurance, infrastructure, and personnel issues involved with running an actual cafeterias, so we had a lunch room with vending machines. So lunch options were bring your lunch or eat whatever you chose from the vending machines. Juniors & seniors could leave campus for lunch, but there wasn’t much close by.
The sandwich machine usually got cleared of anything decent by the upperclassmen. Chips, cookies & candy bars are tasty, but not nutritious. The hot vending machine had cans of Vienna sausages, chili, and a couple of other options.
I brought my lunch almost every day for 4 years, but occasionally, I had to resort to vending. And Frito Pies were the only hot dish I’d eat out of the machine.
Unfortunately for ME, I had an as-yet undiagnosed mild allergy to corn. So the combination of greasy, canned vending machine chili (with or without beans) and the Frito corn chips was a little extra tough on my guts than for my classmates. Heartburn was inevitable; sometimes worse occurred.
