When I saw this topic, the first thing I thought of was cat food And a gallon of purchased drinking water - because my tap water tastes terrible.

Things I usually have on hand - a box of cereal and a quart of milk; cottage cheese and some sort of canned fruit; a box of pasta; eggs, butter, sugar, flour, tea bags; bread and peanut butter. You're getting the theme here, very quick meals I can just throw together. In winter I generally have a few cans of soup in the house too. Couple of bananas or apples, because it's just me I only buy enough fresh fruit for the next couple of days. If my dad buys a cantaloupe, strawberries or a wedge of watermelon, when he cuts it up he will set aside a little of it for me. I like to buy that stuff off the supermarket salad bar. It's more expensive that way but I can get just the amount I need.
