Great ideas. I have a kindergartner this year and we are on week #4 and the menu is looking pretty boring so I will have to try some of these. I tried rolling up ham around a piece of cheese with a toothpick in it one day and he didnt eat it. I thought he would really like it too because it was different. So those of you who use a thermos, what do you to prepare the thermos for either hot or cold stuff? Sounds crazy but I have never used a thermos before because we have always had a microwave available. Do you put hot water or something in it ahead of time then put your hot food in or do you just put your hot food in and it stays warm in the thermos? It will need to stay warm for about 4 hours - is that possible?
