perhaps a dog bowl is basically the optimal bowl
they tend to be plastic (and microwave safe?)
food safe
have grippy handly thingies separated out so you're not holding the hot part of the bowl
suppose the big downside is that they tend to have pretty thick rims and thus would be... not the greatest for sipping a broth from..
an aluminum straw could solve that pretty easily, and i'm pretty sure the strangeness of that kinda went out the window ages ago :3
