What to study?

I’m joining the military soon. Since I already have some college credits, I figured I’d take advantage of the military benefit of free college to get a degree. Problem is, I have no idea what to study. I initially dropped out because I just couldn’t figure out what I wanted and I still don’t know. I wanted to be a chef when I was younger so I thought that would be cool! I only plan on taking 1 or 2 classes a semester since I’ll be on active duty.

Any suggestions?
