A third of us are stuck in such a rut that we have the same thing for lunch every day, according to research.
Most common of all is the simple cheese and pickle sandwich, which people tend to eat by themselves, at their desks, in a lunch hour that lasts just 15 minutes.
The survey of 2,000 adults was carried out by the cream cheese brand Philadelphia, who have some handy alternatives for hungry workers as part of its Love Lunch Again campaign.
Independent psychologist Sue Firth said: "Doing the same thing every day is pretty much guaranteed to make you feel bored and when you feel bored your mood drops.
"So push yourself a little. Variety is fun and makes you feel great, surely that’s a good enough reason to try something different.
"With a bit of effort you can make your lunch great again- get excited about the food you make, step outside, make it sociable- that way we can all learn to love lunch again.”
