I was just in that situation this past weekend, except I was on a weekend trip with a friend. We were at their lakehouse and basically all they eat around there is fast food, ice cream bars, and cookies...exactly what I won't eat! So I actually brought a whole bag of food for the few days I was there, and here are some ideas:
English muffin
sandwich baggie of oatmeal, one serving's worth
two slices of bread (To put peanut butter in between)
animal crackers
apples
bananas
carton of soymilk
baggies of dry cereal
make rice at home and keep it in a tupperware type container - you can even eat it cold if needed
raw carrots
tortillas, to put salsa or "whatever" in (if you have a fridge)
