I repackage items into quantities I need, freeze them using freezer zip lock bags (washing. sterilising & reusing them, unless they've had meat/poultry/fish in them}. Breads, muffins, cakes etc., either go into containers or freezer bags in slices or squares which are easy to remove individually.
I also cook in bulk & freeze in bags/containers in individual portions. It's as easy & also cheaper to prepare & cook in batches than in small amounts, especially if you have an instant pot or slow cooker.
For vegetables, I freeze items like leeks, onions, butternut squash, celeriac etc in larger bags & just take out what I need as & when.
I have lots of frozen homemade 'ready meals' like cottage pie, aubergine & chickpea stew, chicken/pork/beef curries & stir fries in small reusable containers, labelled & dated, which I can easily defrost & reheat in microwave.
I also keep an 'inventory list' of what is in each shelf of the freezer, plus amounts, so I know where to find what, at any time. (As long as I remember to add/subtract the amounts when I put something in or take something out}.
I keep my list on the door of the freezer with magnetic peg.
For store cupboard items, I have yet another list, on the door of my stock cupboard for adding items that need replenishing, so when an item is getting low or is finished I can keep an eye out for the 'specials'.
Also means I don't have to search through cupboards to find out what I need before shopping day.
Sounds very boring & time consuming, however. once you get into it, it can be quite fun, easy to do & only takes a little while to replenish your stock once a month or so.
I also use a weekly meal planner, so can look at it to see what raw materials I need to take out of the freezer in advance, this also allows me to check out the 'specials' on sale instore & plan for my weekly fresh ingredients, like fruits, salads, eggs etc.
