In reply to CJD: Jay's got a great cookbook from the works of somewhere like that on salads.
step 1 night before work open book at main course salads, start at the beginning of the chapter and work through one recipe a day.
step 2 chop up ingredients and place in his and hers lunchboxes, dressing in a small screw top jam jar
step 3 put the lot in the fridge
step 4 wake up 10 minutes before you need to leave for work
step 5 Look smug at lunchtime while you devour fresh meal while others eat soggy sandwiches and canteen crap.
Personal favourites are
smoked trout with rye, emmental and watercress
Greek salad
Chickpea salad with sliced radishes and honey chicken
tomata and onion with balsamic dressing and a hunk of bread to mop it up.
Hummous and Guacamole with crunchy veg and oatcakes to dip.
