I bought a wheat fiber nooblet bowl with a lid form Amazon. I use it for eeeeverything. It's originally made to cook ramen in but since the boiling water + wait method is the same for huel, I thought, why not?
It works perfect! Best bowl I ever bought and I highly recommend it for h&s.

That's the one I got. It's big so it holds a lot and the lid is sealed. You can also put it in the microwave if you like, too. I use this instead of the pot and it's much easier. The pot is just too small for me
