My parochial school cafeteria options consisted of:
Monday through Thursday either hamburger or hot dog
Friday - tuna salad sandwich...
And milk of course. Plain or chocolate...
My parochial school lunch room experience was not the norm. We had an awsome lady in charge and she made sure we had food. Chili, bierocks, mashed potatoes with a beef roast gravy, burritos, homemade pizza, chicken pot pie/noodles...we ate well. I remember a lunch card was 18.00 and we got 20 punches/card. Of course, I did take my lunch too, Mom made sure i had food. I was really blessed growing up. Shame it took so long to realize it.
