This is probably a long shot, but does anyone have a good recommendation for a small microwavable, reusable container (preferably plastic or otherwise hard to break)?

I often cook up rice and break it up into ~100g portions, which I freeze and re-heat later. Right now they take up way too much freezer space because I put them in Hillshire Farms containers.

I have a bunch of 4.5” x 4.5” x 2” rubbermade containers that are about the right size, but if I microwave those they usually develop pits or cloudiness.

I’d love something small and shallow like that, but made of gladware or something.
