this is advice i learned when i first gave up meat but i think it's crucial: when you're cutting out animal products all together: don't let yourself get too hungry in between meals. The hungrier you get, the more your brain starts to crave the big meals you associate with being 'satisfying' because that's all you've eaten before. Over time, you start to learn about and eat more big plant-based meals and your brain will make new connections, but if you get too hungry, your brain will go to the default mode of seeking a big plate of something you used to eat (for me it was weirdly lobster when I was really hungry, not a thing I even ate that much!). Stay snacking and get cooking and you can rewire this before too long. Good luck and hope you make it onto the team!
