Mine was sitting patiently in the fridge waiting for me to make it again, I started making my own lunch at work since late November, used to be sandwiches (hmm chorizo)
But starting this week its been salads so far this week I've spent £7.50 on it I'll be quite happy if I can do all 5 days at work for that money

but I reckon I can get it cheaper if I'm not lazy and go to the Market instead of the supermarket
This weeks salad
Mixed leaf salad (generally bits of different lettuce)
Beetroot
Spring Onions (just sprinkle a few on top)
Slices of turkey meat (unfortunately processed)
Cherry Tomatoes
Vinagerette dressing (low fat)
and Watercress (of the big variety not the tiny small stuff

)
