We bake or make a lot of items to take with us on trips prior to going. I pack things in individual baggies or hard plastic containers. Homemade muffins. Peanut butter and honey or jelly sandwiches (no fridge needed!). Trial mixes. Dried Fruit. We like the Go Picnic boxes (not all are gluten-free, so watch that ..not sure on soy for those). Apples. Jerky. Popcorn baggies. Carrots. NoGii protein bars. Individual humus packages (no fridge if buy it like that premade ones) or individual peanut butter packages and eat with crackers/carrots/celery sticks.
