I used to go to Subway a lot because it was cheap. It’s not so cheap anymore - prices seem to go up every time I go in.
I get the Spicy Italian on Italian herb & cheese bread, take it home cold, add extra cheese and bake it myself. Makes a decent sammich, but don’t go as often since the price went up.
When I was in college I got to eat at the training table and was in hog heaven.
Many years later I went to grad school and my finances were really tight. This was in the late 80s. I discovered that Wendys had a salad bar for only a dollar and it was all you could eat.
I would get a little lettuce then pile on several types of meat and things like cheese, croutons, dressing, and tomatoes. Literally all I could eat for a buck and it was good.
They must have caught on as I noticed a few years later that they either did not have salads or handed them out already made.
One other trick was the university had fish, shrimp, scallops etc. on Friday night for the regular price. I lived off campus but it did not matter. I would fill up on shrimp, scallops, crabs etc. for around $3.50
Still not as good as training table at Troy. Those Black cooks could make turnips taste great and it had a lot of meat it in. Otherwise I usually don’t care for turnips.
