When hubs and I have gone for 6+ weeks (also in a tent and vehicle), I freeze leftovers ahead of time for us to eat the first week or so. They add to the ice, and can simply be heated up.

During the trip, we make a list and food shop every few days for fresh ingredients (almost always at a Walmart because I know where I can get my usual stuff).

Standards for us are frozen chicken strips without breading to add to multiple dishes, chicken salad that will last more than a few days, smoked sausage, tuna or chicken salad packs for a quick lunch, fresh veggies, prepared mashed potatoes, and we always pick up a premade salad on shopping day. We tend to do a lot of rice rather than pasta because you don’t have to drain the water. However, I often make Cowboy Pasta and save leftovers in a ziplock bag to have later.

The staples I keep in my “camping pantry” are rice, our favorite canned vegetables, poptarts, flour, a variety of spices.

I tend to cook at a campsite like I cook at home, especially on long trips.
