Adar Gone fishin'.
is not junk food (unless it’s loaded with sugar, you gotta watch that.)
I keep an individual pack of salmon jerky in the car. It’s expensive, yes, so I am not tempted to snack on it, but when my body is howling that I need to EAT but there is no time or worse, nothing but fast food is available, I can eat something quick and nutritious. I think of it my “break glass in emergency” food.
