Well I'm not sure where you are working these days, but I was in London last week and found the best salad I'd ever eaten. I got it from Leon (there are 8 in London - dunno if you ever go in there?). I had an original superfood salad (broccoli, avocado, quinoa, peas, feta, alfalfa and seeds, with lemon and olive oil). Cor it was so nice I had it three days running.
They also have sweet potato falafel that are v tasty (though I suspect you dislike sweet potato - can't remember for sure). You can have em in a wrap with slaw or you can have em with brown rice and other stuff. Breakfast is good there too. I had porridge with strawberry compote, and a carrot and orange juice.
When I come down to Hyde Park for the run this month I will be going to Leon for my lunch
