Breakfast: Oatmeal, cream of wheat, grits, tea, hot cocoa, dry milk.
On trail/Lunch: Jerky, dry fruits (pick fruits without fiber or you will have to dig many pits), Powerbars/Balance Bars, trail mix, nuts, Chex, Rice Crispie Treats, Tiger's Milk bars, chocolate, cheese sticks (if not over 70 degrees), crackers, peanut butter, salame, honey.
Dinner: Rice, pasta, couscous, noodles, mac&cheese, pancake mix, grits, tuna (if not in bear country), salame.
The rules of thumb:
Breakfast: something dry, easy to carry, and preferrably warm.
Lunch: Something easy to eat on the trail. Try something that is light, low in moisture, and high in calories. Any meats should be the kind that are dry and don't go bad easily (like jerky and salame)
Dinner: Anything that is light and blows up in volume when you put in water.
MRE's are OK, but are heavy.
Unwrap everything and mark the inside of your cups for measuring. Write on food packages how much cup volume makes a serving.
Hope this helps. - CAman
