Why Am I Obsessed With Ordering the Same Salad Every Day?

I'm 27 and I have this weird compulsion to order the exact same salad every single day for lunch. It's like a bizarre ritual, baby spinach, grilled chicken, cherry tomatoes, cucumber, red onion, croutons, and bleu cheese dressing. Not too fancy or expensive, but it takes up my whole lunch break because of all the prep at home before I head out to work. Every time I try to switch things up, like going for a soup and sandwich combo instead, I end up backtracking as soon as I hit the office to order that salad from my regular deli counter across the street. There's this part of me that enjoys variety and trying new places, but it seems stuck in some kind of lunch-time loop. I've even started feeling self-conscious about it. My colleagues joke around that they could set their watches by when I hit up 'Salad Lady' every single day. Plus, there’s this guilt thing, isn't there more to life than a lettuce salad? It's like an addiction but not exactly satisfying either. Am I just being silly for feeling weird about such a mundane habit? Or is it actually something to worry about and break out of? How do people get over their lunchday rut?
