I try to make my lunches creative for my kids. They seem to eat better when it is not PB&J or macaroni and cheese everyday. Some of the things that we do for lunches that are favorites are:
quesadillas, pretzels and peanut butter, homemade lunchables (crackers, meat and cheese) bagel people, ants on a log (celery, PB, and raisins). These are just a few of the fun things we do, and not everyday, we do have PB&J (it's my 4 yr old's favorite lunch of all time).
Today we did bagel people. We use plain bagels, cream cheese as a base, and then decorate with whatever we have on hand. Today we had lunch meat, olives, blue berries, shredded cheese, pickles, strawberries, and string cheese. You can use any fruits and veggies that you have available (peppers, lettuce, chives, carrots, peanuts, parsley, tomatoes).
I add a little layer of cream cheese and then let the kids build their own person. They are very creative, sometimes we have mustaches, glasses (like the bottom pitcure) crazy hair, but whatever they make the kids seems to love. And they eat them right up.
