I can pack 4 days worth of food in my bag, but it might not be that appetizing to you. I pack 1 to 1 1/2 loafs of bread, peanut butter, jelly, two packs of individual no drain tuna, 4 packs of individual mayonnaise I pick up from whatever fast food place I pass on my way to the plane, 2 plastic bowls of soup, 4 packs of peanut butter crackers, about 10 granola bars, and a couple of fruit cups. Sometimes I also make a 1/2 gallon size bag of trail mix.

I don't get anything that needs refrigeration because it is too much of a hassle trying to find refrigerators at about half the hotels we stay at. I also drink about 2 gallons of water a day. All that keeps me full, awake, and a little richer as I pocket my per diem.
