This is what Tina did:
The meats are precooked. Then you just add in some individual servings of frozen veggies his fav or potatoe fries or steamer potatoes all in the bag. All he has to do is open season n heat. I also write out a lil instruction on front of ziploc if there is a non-perishable item sent with supplies like easy mac or something that doesnt need refridgerated.
If you have the possibility it would be even better to vacuum seal the food so it will last longer. Of course you will need a fridge or cooler. The bags will last longer vacuum sealed in a freezer or fridge but this is a great way to save on meals and make it easy on the road.
You can even do this when you are a solo or team driver. Make a menu for the week for instance but make dishes using many of the same ingredients for instance chicken for meat but you could make pasta one day, with potatoes the next etc. but you could buy a big pack and split it up. The possibilities are endless.
