we usually keep it basic. trail mix (nuts,sultanas, cherios cereal) biscuits and vegimite sandwiches.
frozen poppers are a must have too

Chips & shapes LOL

Mine also love carrot sticks and baby cucumbers (whole)

Carrot sticks, pop corn, protein bars (home made)

We like fresh fruits and veggies, roasted broadbeans and chickpeas, or roasted mung beans from the Indian Isle in the supermarket, nuts, trail mix, sandwiches, buns or wraps, homebaked sweetpotato waffles or veggie muffins, unsweetened greek yoghurt with granola/muesli, fried up tempeh (fermented soy, we’re vegetarians) or for non vegetarians cooked chicken, boiled eggs, etc

Chips, drinks, sandwiches and whatever we find on pit stops!

Love everyones answers, but I especially love to pack a thermos full of coffee or tea. You can always pull into the ‘pitstops’ and have a nice cuppa!

Nuts, grapes, cookies, yoghurt, cheese strings, chips, m&m for a little treat.

I always pack fruit, nuts, cracker biscuits, and popcorn.

I usually pack plenty of fruit, some nuts (either mixed or single types) sometimes fruit and nut mix, air-popped popcorn either pre-packaged or cooked fresh in zip lock bags. Biscuits and cheese if a cooler bag is available. Banana bread – great taken in frozen slices individually wrapped – by the time you are ready to eat it has defrosted but is still cool and moist.

I stumbled over broad beans and the kids love them. You can buy them in the health food isle of Coles and Woolies and come in a few different flavours and in snack size bags. We call them magic beans and the kids think they’re magic.

Mine love cherry tomatoes and baby cucumbers

jatz, grapes, olives. you could put toothpicks in them to keep your hands clean but i always have wipes in the car.

I pack small celery sticks, carrot sticks or small pieces, Kabana whole which is sliced on the way and a container of dip usually capsicum. We keep all this in a small car fridge run on the car battery. It also pays just to rink bottled water on long trips. We travel to Rockhampton every 12 months [ just short of 2000ks from where I live] and find that works well.

things that are easy to eat and not going to make too much mess – apples, sultanas, cheese, crackers, trail mix

The thermos of soup is a brilliant idea – love it.
