I try to add something "alive" to everything my kids eat. So even if they're having a ready-made thing I put it on a plate with some fruit or veggies. The key is put a variety of things on the plate/snack box and then it's interesting. There are lots of excellent salad veggie things that kids love - from celery and carrot sticks, through mini-tomatoes and sprouts, snow and sugar snap peas to those miniature baby cucumbers (my kids *love* them). There are lots of different crackers on the market - many of them have a wholegrain element - some have mroe additives than others but in small amounts they add interest to the snack/meal. Also cheese comes in a lots of different configurations, you can add nut butters or cream cheese or hommous to the plate for the kids to "dip" in. Chuck some dried fruit in - blueberries, cranberries, dark raisins and currants all have excellent antioxidants in them, but even dried apple, peaches etc are good. My kids also love having yoghurt with a sprinkle of muesli or whatever fruity-flakey cereal we have at the time. Fruit is good and if you're a bit creative about cutting it into different shapes or serving it with different things they will love that too. Just keep rotating how you serve them up and the food will stay interesting .
