Oh totally it can be done easy, and there are some packaged foods also that are not terrible that you can use also. There are soooo many things you can make and freeze - I actually think it's harder to provide variety with all the packaged stuff and expensive, sure your child will see other stuff & might ask but they will eat what they are used to.

You can get kids thermo's for leftovers.

I always put 2 serves of fruit in Charlie's lunch for Kindy. Today was a banana and a pair, also I put in what I want to eat....given no choice if he is hungry he will eat. Toaday's lunch box was, banana, pear, yogurt, whomeal cruskits with vegimite and a couple home made cookies.

You can make Pikelets (plain, with banana, with appple etc), savoury slices, savoury muffins, sweet muffins, banana bread, cheese & vegemite scrolls, scones, pizza scrolls, pinwheels, pancakes, cookies, muesli bars, trail mix, sausage rolls (full of vegies), pasties (full of vegies), cakes soooo many things.

We also use raw nuts, dried fruits, cereals (some make good snacks), grain bread sandwiches, whomeal crackers with cheese, dips. Vegies with dips.

Ok that's all I can think of now with screaming baby at my feet. Hope that helps.
