Since you're most interested in a side business with low investment/time commitment, I would recommend using that 10k to get an online biz. Look to buy a website(s) through Flippa or Empire Flippers. Returns will blow stocks and real estate out of the water.
Or start your own online biz/website. Once you come up with an idea, head to UpWork and hire freelancers to do everything you need. You could also start an ad campaign on Facebook or Google.
