DH is doing rigging at a refinery shut-down so really can't go out to get lunch without showering first (they're working with an area that has had toxic chemicals) - so I have to make him enough to sustain him during the day

This is what I do for him (he starts at 6:30 & finishes at 5:30pm so needs arvo/morning tea plus lunch) - this is what tomorrow's food will be:

Lunch
500ml Tupperware container with:
ham (about 5 slices from the deli sliced into thin strips)
cheese (about 2cm thick diced into chunks)
2 mushrooms sliced
1 tomato diced
handful of mix lettuce leaves (largish handful)
mix of sprouts (mung bean etc)

Morning Tea/Arvo Tea:
muffin/cookies
cheese & bikkies

today he got steamed veges from last night (all organic) with rosemary & lamb organic sausages for lunch, a couple of muesli bars and a tub of yoghurt

I do similar for me but on a much smaller scale - I also make up toasty packets on the weekends and freeze them - I wrap the bread with filling in glad-bake and then put them in the freezer - which means I don't have to make the sandwich in a dirty sandwich maker as it is encased in glad-bake.
