I use to do a lot of the Campbell's chuncky stews. They are amazing. So many choices. Haven't had one I didn't t like. I started doing that on my kayak. Cant get smashed, or wet. Compact and easy. Summer time let them sit in the sun and they get warm. And the have a pull top. Also canned fruit. Peaches pear cocktail. Now I usually get a breakfast sandwich and a deckhand sandwich from dana landing market
If you have a Sprouts/Whole Foods/etc nearby, you can get good beef jerky without all the salt. It's pretty much a straight shot of protein and you can shake it out of the bag into your mouth if your hands are a mess. If I'm not leaving at the ass crack of dawn, I usually take a double scoop protein shake knowing I can take a shit at the Dana Point Marina offices (they also have super cheap ice). Learned the hard way to not assume they were open just because the gate let us into the parking lot.
