have only hiked Hawaii on long multi day trips but I can add:

1. GORP (granola, oreos, raisins, peanuts. Can substitute m+m s for the oreos) 2: dehydrated meals by Mountain House, or BP Pantry etc. bring spices to taste.
2. any dried fruits to choice.
3. energy bars.
4. find local food in the hiking area you can enjoy, fish, harvest, scavenge
5. have the other people carry more of the weight. Don't believe everything you read.
