First of all, congrats! And thank you for letting your compassion and empathy affect change in your life and the many many lives of animals.
Second, meal prep. Get some good Tupperware (I use the Pyrex snap wear stuff) and learn some recipes that taste good leftover or even cold.
Lastly, Always have something to eat with you. Protein bar, fruit, or a Tupperware of leftovers.
Good luck!
