Best Huel meals/snacks for when you need to concentrate?

Hello Hueligans,

What are some of your favorite Huel meals or snacks for when you need to concentrate? I am a grad student with learning difficulties and looking for ideas for study snacks. I just did 1/2 a black edition shake, which was convenient since I could drink it while studying. I hope it will keep me full for a while, as hunger can be so distracting.

Thank you in advance!
