Some more ideas and I use this with my kids and it works well.
Kebabs
I make mine with whatever ground meat (mostly beef but sometimes chicken as well). Season it however you think your kids will like it. I am Indian so my kids are used to the spices. I season mine with ground cumin, corrainder, chili powder, cinnamon, black pepper, freshly chopped corrainder leaves and mint leaves and some grated ginger. Mix it together, marinate for a little time, make patties or sausage type kebabs, grill or bake in the oven and freeze them in foil (individually or two or three small ones). I reheat them in a skillet and get them nice and hot. Wrap them tightly in foil and off they go to school with my kids.
Patties:
Boiled potatoes, shredded chicken, freshly chopped cilantro, finely chopped bell peppers (red, green, yellow), seasonings like black pepper, ground cumin and a finely minced jalapeno, slat and mix it all together. Make patties. Dunk them first in bread crumbs and then in egg and fry it. These freeze very well too. Warm in a skillet, wrap in foil and once again off they go.
You can make a sandwich out of them or just send them as is to school.
Egg Sandwich
Cut a nice size square from french bread. Slice it from the middle and toast it in a toaster oven. Crack an egg in a microwave safe bowl. Microwave it covered for a minute (I beat my egg slightly with a pinch of salt and black pepper). On the toasted bread add a slight spread of mustard (I use the stone ground honey mustard) then place the egg on it. Next goes a slice or couple of slices of cheese and then finish the sandwich. Again wrap in foil and my son cannot stop raving about how good it tastes even at room temperature.
A lot of kids are pretty finicky so these may work or may not work. My kids are pretty adventurous and will eat different things (including different kinds of foods and cuisines) so I can push the envelope with them. They like regular kids favorite like nutella and pb&j but the ones I listed above are also a real hit with them.
I also send in eggrolls and samosas from time to time and my son loves to eat them at room temperature and they are not only a hit with him but also with his American friends. He always takes more and shares
