This is the BBC.

Hello, you've downloaded a podcast of BBC Radio 4's The Food Program.

Welcome to our world, from cooking to culture, politics to pleasure. We hope you enjoy it.

There's a pretty mundane grey dreary place where every day feels pretty much the same.

I only get half an hour for lunch and I've found after 70 years of working

for that place that I've got a very, very routine, carefully nuanced system. Tin, pink salmon, own brand stuff,

a good handful of sweet corn,

with a little bit of dill, you know, for some character.

A tablespoon or two of mayonnaise in there that I make myself two really big

salmon sandwiches. I've got a can of own brand tomato soup on the go and yeah pretty much every day I have two whole

sandwiches dipped in tomato soup. Always the same and as John Humphrey's

discovered last Monday commoner than you think.

Millions of us, when he comes to lunch at any rate, there's a new survey that suggests that more

than three quarters of office workers have eaten the same midday meal for the past nine months.

Since the 1980s, I've been eating a tuna, mayonnaise and salad sandwich or roll for lunch.

Every day I know when I see a certain customer in the queue,

I know what he's going for.

For me, it is always a tuna sourdough baget.

There are certain days if I'm feeling just quite distracted

where I don't really even notice what it tastes like to be honest but there are others

where, mmm salmon and soup. Does the British lunch have a future?

Not long ago we got together with BBC Good Food magazine
