Thanks for the replies! They're all very helpful. That gives a lot of good choices; white quinoa, bulgur, pastina, regular couscous, polenta. Red/yellow lentils as well. I have brown lentils and they're soft if cooked long enough but it seems they have some outer skin that irritates my teeth but maybe the red/yellow ones are softer.

I had one of the worst toothache last night after eating a fig bar, so I'll probably just make the all of the above and just drink. If they're is no large chunks then it should be easy to drink.

Thanks again!
