For Breakfast:
I like taking 2 hardboiled eggs per person (boiled at home and ziplocked), 2 biscuits per person (baked at home and ziplocked), 1 or 2 packs of instant grits or instant Oatmeal(per person), raw bacon for cooking if water is not an issue, or a canned meat such as SPAM (1 can per meal).
For Lunch:
I no longer carry a specific meal for lunch since I/we have never slowed down enough to prepare and eat a lunch. I/we carry a couple of different Trail Mixes, energy bars, cheese and crackers to eat at lunchtime and in between meals.
For Supper:
I will normally carry an MRE or a can of (Beef Stew, Chicken & Dumplings, Chili, etc) aka: C-Ration and some crackers.
Breakfast normally stays the same but I/we do something different for each Supper that we are out.
