I had mayonnaise sandwiches, like you, if I had bread.
Prosciutto, hot capicola, Genoa salami, provolone with lettuce and tomato and oil and vinegar. Some oregano and pepper. Bread has to be NY Italian bread.
That and an ice cold beer and I’m set.
To this day I keep a box of Kraft mac n cheese around. No milk or butter? Use mayo. Add tuna back then or hot dogs.
Always kept tortillas. Heat and butter. Rosarita refried beans were cheap.
Vienna weenies in the can.
We had lots of pinto beans and fried potatoes in the 60s.
Ever since I was 14 I have worked mostly in places that had food. Restaurant, pizza delivery, grocery stores and lots of hotels.
