Having a few as comfort food is OK, but if you check the nutrition label I believe these are really high in sodium and lacking in food value.
I keep a .50 cal. ammo can in the truck with shelf stable "over the road rations" and cooking gear to avoid having to stop at fast food joints. Has been helpful when traffic stopped due to winter storms, etc.
I carry an immersion heater which fits the cigarette lighter plug, Mil-K-818 pocket knife, GI canteen cup, Natick cooking stand, Esbit fuel tabs, BIC lighter, mess kit spoon and fork and 2 gallons of water.
In the food can are four small tins of evaporated milk, instant coffee, tea bags, cube sugar. 1 tin or jar each of peanut butter, fruit jam, canned chicken, tuna, corned beef, pork & beans, an 8-pack.of 6oz low sodium V8 and Sailor Boy Pilot Biscuit. All of these can be found at the grocery except for the Pilot Biscuit. Saltine crackers with unsalted tops or Wasa Krispbread could be substituted. Suggestions here are offered as an idea starter for discussion only.
