Olives. They sell those in snack packs now at some stores...
Macro Bars
Some stuff keeps better than others so that's also something to bear in mind.
Seaweed snacks
Sardines
Carrots and guacamole dip (another thing that won't keep long depending on how you store it, store bought should be ok so long as it's unopened)
As we say, the kids are professional eaters. Since we have to deal with food allergies, any trip, camping or not, requires a meal plan. My kids are 4, 2, and 1 and they dang near eat the same amount we do.
Hope you found something helpful in all of that lol.
