Would cooked quinoa stay overnight? I cooked quinoa like rice and ate half of it. I am planning to have the other half for breakfast. Is it safe to leave it in room temperature overnight (I don't have a refrigerator)?
There's some good advice here:

In summary, everything goes bad, quinoa is no exception. To be safe, refrigerate when possible. Leaving food at room temp is asking for trouble.
