:What a great question. A lot depends on your tastes I keep staples on hand ,foods I really like and can always eat such as cans of tuna and salmon , sardines , boxes of oatmeal, eggs , cheese, brown rice cakes, peanut and almond butter, nuts and potatoes.
I buy fruit and vegetables on Saturday at the outdoor market and make a large vat of soup with about six or seven of the vegetables. Portions of this are frozen.My meat or fish for the freezer includes sausages, bacon and ground beef for meatballs. I have good intentions for buying more frozen fish but that has not happened yet. I look forward to reading more shopping lists and more tips and would like to make more gourmet meals but always seem too busy..
