In general, food-stuffs should be varied enough so that eating is a joy, quick to cook (no "simmer for an hour" things) and produce minimal trash. Repackaging may be a good idea in some cases.
I am personally not a fan of elaborate camp breakfasts. There are options involving things like dehydrated eggs, bisquick, etc. ... but, I'd usually rather get going early and enjoy the natural morning light.
- granola bar
- dried fruit
- fresh fruit
- fricken' heavy, use early
- instant oatmeal
- peaches&cream is my "favorite" ... a term I use loosely. requires cooking AND cleaning.
- hot tea
- requires cooking, no cleaning.
I'd usually stop for a proper "lunch" if there is a good spot to do it: no bug issues, some kind of interesting view or otherwise good resting point. When this isn't possible, I'm more likely to graze on food during water/photo breaks.
- trail mix
- melting issues
- nuts (almonds, cashews)
- dried fruit (raisins, craisins, banana chips, other)
- hard candy
- certs, altoids, runts, etc.
- pretzels, tortilla chips
- pre-crushed to save space
Additional foods with potential spoilage issues
- hard salami / pepperoni
I make it a goal that every evening includes a meal that I'm looking forward to. This is why you won't see "ramen" in my list.
- freeze-dried meal things
- pros: taste amazing, decent variety, very filling, and are designed to be pretty complete nutritionally, no cleaning necessary (eat-in-bag)
- cons: a little pricy ($5-$7 each), a little bulky, unsure about availability in Peru
- dried soups
- pasta w/ red sauce
- fresh veggies
- like fresh fruit, fricken' heavy, use early
- dehydrated veggies (e.g., mushrooms)
- bouillon cubes
- random lightweight spices
- little packets of spice I have saved from various places. packages burnable.
- powdered ice-tea
