it all starts with spices for me, gotta get it from an organic market not that irradiated crap they sell in the supermarkets. i'll buy big bags of whatever's fresh, dose it out into smaller containers for immediate use and keep the rest sealed in mason jars to keep fresh.
herbs are key too, prefer to get those wherever they're freshest and buy as much as you can get then wash them in one go, shake the water off, roll them up into ziploc bags like you're rolling a fattie and then put in freezer and you have fresh herbs on demand that never wither.
goat cheese is fucking delicious. i've honestly never had any type of goat cheese that wasn't superior to dairy cheese. you might have to go out of your way to find a good goat cheese supply, but it's
worth it. i go through a fair bit of goat feta since they come in convenient half-kilo bricks and are great with eggs or salads in any quantity. goat feta lasts literally a year in the fridge, so you can buy 2-3 kg at a time and just make it a staple food if you like. lactose-intolerant ppl can also enjoy it.
vegetables that don't get much exposure and are easily washed (eg. Bell peppers) don't need to be organic as far as i'm concerned but for stuff that grows close to the ground and has nooks n crannies i would go with no less. for meats and eggs usually i'll go with "organic"/free range but i don't eat that much meat so the quality is worth the price difference. if you've seen Food Inc. or docos like that you wouldn't eat the store brand stuff either. what they're allowed to and actually do put in that stuff is so disgusting and definitely not reasonably fit for human consumption.
onions and garlic are must-haves for any sort of legit cooking (in addition to spices, ofc), carrots and celery and other root vegetables can come in handy for big hearty meals like chili/stew and the remains you can still use in soup so they're good to have in the fridge and then you're pretty much forced to make some tasty, wholesome food with them.
mushrooms are often overlooked but they're really popular with beef and you're likely to find some sort of beef and mushroom dish at any restaurant. they're easy as shit to dice up and either sautee with something tart (eg. wine) or add to a soup or stew.
random advice:
talk to the fuckers at the store and get their shipments schedule, go for the foods you want on the days they get them fresh, especially for staples like bread and eggs.
buy strange shit like endives or artichoke and figure out how to use them
find a market that goes to great lengths to procure fresh, exotic fruits and buy all your fruit there. seriously, supermarket fruit is seldom ever better than shite, no sense wasting your money on it there when there's a market out there that can supply you with grapefruits sweet as oranges and mangoes that will make you forget you're sober.
freeze anything you don't plan to eat within the next two days, and don't buy raw meat or fish when you haven't figure out what you're going to do and whether you even have time for it.
explore oddball condiment combos. pickled beets with horseradish are actually pretty interesting. legit sauerkraut (just salt + cabbage) is healthy as fuck and goes DAMN well with beef stew or weiners.
that's all i got for now. it seems like a lot but with shortcuts and the fact that a lot of stuff can be reused in a number of dishes it's not as daunting to resupply as it seems, just have to find your rhythm and then you'll be capable of the zen art of shopping without a list and never having anything go bad on you
