Turkey and Chicken dinners that need no refrigeration and are heated in the microwave. OK , you dont have a microwave in your truck but you can boil water on a fire, drop one of these in a pot of boiling water for 10 or 15 minutes and you have a pretty good hot meal. I found these last year and have brought them on several kayak trips and they have worked out well, they don't take up cooler space so there's more room for cold beverages and they taste better than freeze dried stuff.

 

Nice. I will look into these for the next wheelin/camping trip
