I am interested in discussing food for a long (150+ mile, 12+ day) backpacking trip. Resupplies may not be possible, so I need to plan on carrying it all. Therefore, weight is an issue. Sufficient nutrition content is important. Minimum pack volume is critical.

What are some of the things that you have done on longer hike to keep the food interesting yet meet the weight and volume requirements. Short of prepacked freeze dried food, is there anything that you would use?
