I normally use sugarcane plates for the same reason as OP: I despise doing the dishes. They're surprisingly resistant to leaking (though not completely like plastic).

I used to also cook soaked dried rice in paper cups with a microwave. As well as using paper towels on these plates to bake sausages and fish cutlets (don't go above 180C)

OP, I suggest you use the base and the lid as two separate plates, and tear the boxes at the hinges. That way you save even more and you can stack the used boxes more easily to save space.

Also consider aluminum foil trays if you want to make something soupy.
