I put my eggs usually in like a jar of some sort, put the seasonings in em and everything before we leave so we don't have to bring em. I chop up veggies (onions/peppers) for ommlettes, and I put the steak or chicken whatever we're planning on eating, in a ziploc with marinade. Everything cept the drinks go in ziplocs to keep from getting spilled into the ice when it is melting. Packaged or not. Makes it tons easier
