Out on the water chasing green fish I like to bring either a few *Smuckers Uncrustables or a couple of fried egg sandwiches, beef jerky, dried mangoes and a Snickers bar. A cup of coffee or two to start the day, and water and diet soda to drink.
Going out salmon or rock cod fishing in the salt, I’ll bring some hard boiled eggs, a couple of tuna & onion sandwiches, a couple of salami and cheese sandwiches, apples, water, diet sodas and a thermos of coffee.
*IMHO a pretty good alternative to making pb&j sandwiches, they’re frozen and thaw out in the cooler ready to eat traveling between fishing spots
