I usually eat oatmeal in the morning, and a bag of freeze dried food (there are veg alternatives) and sandwishes for lunch and dinner. Fruit soup from dried fruit and tea or hot chocolate at night. Always keep chocolate and candy at hand. Sweet soup and chocholate are great if the kids are picky but everything tastes better out there, even for kids. If you bring a thermos per person you don't have to use the stove for lunch. Remember to drink fluids even when not thirsty. Dehydration happens easily and will lower body temp, especially in younger persons. Have a great trip!
