Beet Hummus Sandwich

"An ideal lunch sandwich: Sourdough bread with beet hummus, lemon marinated zucchini, avocado, lettuce, and tahini ??? My summer vacation is soon over so I’m thinking about lunch ideas for work. Hummus sandwiches are one of my go-to desk lunches (although they don’t always look as flashy as these ?). What is your favorite portable lunch?"
