My go to snacks alternate between salty and sweet or some combination of both. (Or in desperate times whatever chocolate is available in the house.)
Sweet snacks revolve around dark chocolate. Mostly Hershey’s dark chocolate chips. If we are out of them, the situation is dire and a trip to the grocery story must be made immediately. In the rare chance that this version of chocolate is not available, I can settle for dark chocolate almonds or gluten free thin mints. The problem with these foods is that they are full of calories and writing is fairly sedentary. I do have a laptop platform for my treadmill that I should use more often and that would alleviate some of the calorie load were I to use it more regularly.
