I’m surprised that your Spanish 101 class seemed so limited. We learned a lot more than that in our college intro Spanish class (although I’d already taken 4 years of Spanish in Jr. and Senior High School)
Since it was so limited, I would suggest taking French. At least you’ll learn some words that can be very useful in literature and cooking (if you’re interested in those subjects). Rather than becoming fluent in either of those languges.
I never took any French, but I wish I had now, because my heritage is French and I love to cook and read and often see French words that I wish I could pronounce and know the meanings.
One of my favorite French cooking terms is mise en place (prounounced kind of like meez ahm plah) which means loosely to “put things in place”. What it usually refers to is having all of your ingredients measured out ahead of time and put into separate containers and lined up in the order in which the recipe calls for each item.
The other one that I like is mirepoix (pronounced like meer pwah) which is the holy trinity of French cooking: carrots, onions and celery.
So I would choose French : )
