I usually do a combination of store bought and freeze dried meals.
Breakfast is usually 2 instant oatmeals or home packaged granola and dried milk or Pop tarts and Starbucks Via coffee.
Lunch consists of WW Bagel Thins or Sandwich Thins (hold up well in a pack)with PB&J, or Spam foil pack, or tuna foil packs. Sometimes it might be jerky,or trail mix,or package of PB crackers, or Power bar, dried fruit, etc.
Dinners are usually Mountain House Pro Pack freeze dried dinners or foil pack of chicken,tuna or salmon with a Idahoan mashed potatoes or a Knorr pasta or rice side dish, or Ramin noodles.
Hint after boiling water place the pasta, rice or potatoes into a freezer bag to rehydrate and cook.
No need to mesh up a pot. Also bring some snacks such as trailmix, Clif bars, and granola bars. (look for 100 cals+ per ounce) Usually I package a days worth of food (20-26 ounces) into a gallon storage bag which then becomes a trash bag. I will experiment with different food combos during summer time weekend backpack fishing trips.
