my hubby has a sandwich press at work so he makes his own foccacias for work every day.

if they at the office, i would suggest doing this, or makign over the night before and reheat, we do this with most meals so sandwiches dont become a bore.
if htey eat salads, they are good too...
but he takes fruit and munchies aswell so always has tons of food on him

also with sandwiches what i do, if theres tomato or somethign to go in it, i wrap the tomato separately so that he has to put in in himself and no soggy sandwiches! plus tuna, give him a small tin instead of puttign the tuna in the sandwich...
dont know if that helps, but its what we do for his lunches!
