I've been a vegetarian for over half my life and it's never really a problem for me but I live in California so there's plenty of places to get food w/o meat. That being said, I'm too broke to buy take out so I normally take my food to work (PB&J, beans & rice, etc.) and eat it cold because the microwave at station is rarely clean and it heats unevenly which annoys me to no end. And honestly, on shifts shorter than 24 hours, I don't really get hungry on shift. I load the hump in the am with oatmeal, a couple bananas, and a salad and I'm good to go for up to 12-16hrs provided I've got access to coffee and water.
