Bacon, pre cook 90% before hand, freeze if you want, will keep for 3-4 days minimum. same for eggs, no fridge needed for at least two breakfasts. Pack carefully, Zip lock over container just in case. Chicken/tuna in packets at store, no fridge needed, added to any potato/soup/side dish makes instant meal. Cheddar cheese in block/wax.
Can make pizza real easy. Foccacia, pepperoni, green peppers, Mozz in lump. Squeeze bottle of pizza sauce. Cut foccacia to fit size of fry pan, fry on one side, flip, add ingredients, put foil/lid over fry pan heat enough but not to burn bottom, 5 minutes, voila. Mozz in original package, not shredded, good for 2-3 days no fridge needed.
We bring in small cooler that fits in pack, soft or hard, filled with frozen stuff, precooked fajita meat precooked stew meat, etc. and then add fresh ingredients that keep for a while, green peppers, carrots, etc, to make meal. Tortillas are great. Peanut butter and honey, roll up, yummy. Lots of ideas and not a lot of cost. Absolutely no need for freeze dried if trip is less than 7 days. That stuff is crap!!!
Unless you are portaging miles and miles and weight really counts, that is. Its really expensive and not very filling. Repackage all goods carefully, saving directions, or write them on slips of paper/on bag. Keep meals segragated into break, lunch and dinner bundles in separate containers/bags. Saves a lot of searching hassles. Same for spices, all in one bag.
