A general thought that came from a more specific one I had the other day: I've been trying to make sure I eat breakfast by making overnight oats, but it can be a pain on tired nights to get it set up.

Are there any gotchas with making your own mixes of dry goods? I feel like I know enough to scare myself with things like "oh well that might not be shelf-stable when mixed since xyz pathogen from it grows well when provided with abc".

At the moment, I'm just imagining prepping like a weeks worth of oats, chia seeds, raisins, etc. so that I can dump milk in each night, which seems like it would be totally fine.
