i personaly love having these done BUT just as fair warning-one of my previous co-workers did this for the people she supervised and when human resources heard about it (after the fact) they had an absolute fit, they pointed out that although it was a remote possibility, if one of the staff members who was 'gifted' with this complained that they were injured in the process, it would be considered a workman's compensation issue and the insurer might pursue dropping the bsns. from coverage (or jacking the rates way up). i should say, i worked with allot of 'sue happy' people
how about making up those jars with all the dry ingredients for either some type of cookies or some type of homemade soup. you use mason jars (much less than one dollar a peice when bought by the dozen), put the ingredients in (layered to be more attractive), and attach a note with instructions on what has to be added/cooking times. i've gotten some where a small peice of holiday fabric is put on top of the seal before the ring is tightened. if you're the crafty type you could sponge paint something on the jar (gingerbread man, snowflake). there's also the possibility of buying a 'group gift' for their use at work-i did this one year. i supervised a dozen people and i noticed the long line at microwaves at lunch, i also noticed that people would keep cans of soda at their desk and choose to drink it warm over having to deal with the nasty staff fridge in the break room. i bought an inexpensive microwave and a dorm type fridge (the taller style) which we set up in our work unit. my 'ladies' were able to store their sodas and bottled water close at hand, and they had quick access to a microwave. that was a gift they truly loved.
