For your circumstances, i won't disagreeNoooo! Well, possibly not. Throughout my working life I always left the premises at lunch time, usually to walk to the market to buy some stuff to bring back to eat. By all means bring your lunch from home, but it's important for your health and sanity to get out of the building for half an hour: there's absolutely nothing worse than staying sat at your desk spooning food out of a Tupperware box.

,+1 to make lots of soup and freeze it in portions.
I also do this with ratatouille (which I suspect I can't spell), and a thing called "courgette slice" which is just a good way of using up courgettes from our veg box (my boyfriend doesn't like them, I do, but I do sometimes wish we didn't get them quite so often!)
Otherwise I have lots of salad and fruit.
Fair point. As you say, I was sat down most of the day at the same desk, so the activity was good. Mainly though it was to get out of the immediate work environment and flush out my brain, which IMO is valuable....but...
I'm on my feet or walking round the plant most of the day...i just ache to sit down for half an hour,
Now, getting out of the building...i'd go with that regardless. Fat chance though.
Do you mean a roll or something? Not usually. My idea of soup is usually something that is very thick and filling, so I don't feel the need of anything else. I'll have an apple or so to fill up. I don't feel that I have a limit to how much fruit and veg I can eat! (Not that I am claiming any kind of perfection - I also visit the vending machine at work too much...Not being critical but just interested.
I eat a fair bit of fruit and veg but overall in my diet I find there is a limit. Do you have some carb with the soup and if not why not?

This is going to haunt me more than global warming!It's OK, I've just had an extra thick layer of butter on a couple of soda farls to get the quota for the UK back on track due to the shortfall caused by this kind of piss-poor 'no butter' nonsense. An accompaniment to left-over chilli (made with Gran Luchito paste)..shlurp!
I'm having a "bored with butties" period and have rediscovered tins of mackerel with couscous (especially since divvying up a kg bag and assaulting the spice rack works out at less than 15p a go).
But, is 5 tins of mackerel a week too much?
It'll only be for a month or two until I get bored of it but think I've seen recommendations to only eat 2 portions of oily fish per week.
On a Monday I make a big tub of the following, put it in the fridge and take a 5th of it every day in a pot.
A packet of uncle bens while grain express rice
Chopped mushrooms
Hienz mixed beans in spicy Tom sauce
A packet of cashews (increases calorie count a lot)
Packet of pumpkin seeds
Chopped celery
Chopped cooked chicken breast
A large dollop of salad cream (turns the spicy Tom sauce into a Marie Rose sauce)
A twist of pepper
