Do they deliver? Could you ask a friend to do a shop, maybe offer them petrol money? If you are not there, you will not be tempted.
Also rural and have chucked a ton of food out over the year due to anxiety levels, shoddy fruit and veg, dodgy fridge etc. Quite reliant on freezer. All supermarkets who deliver to us send us the skankiest of fresh veg and I have just given up.
Pak choi lasts a good 7 days. Butternut squash will sit without ruining for two weeks. Courgettes easily last a week in a good fridge. Frozen cubed swede and sweet potato can be done in an air fryer or oven any time. Also diced onions. Won't freeze well if you get full onions and DIY. Frozen mushrooms a bit gross but you defrost them on kitchen towel to soak up a lot of the moisture. You can get vacu pack packets of large corn the same as corn on the cob and they last months. My other half heats frittata from lidl for £3 for a massive one and they last months. He has them with coleslaw and potato salad that generally lasts a week. Frozen stir fry veg. Frozen almost anything veg these days. Fresh baby corn will last a good 5-7 days.
Do you have a farm shop? Do they do onions on chains? Because they haven't had the top bit cut off, it's intertwined, they last MONTHS! But our local is hit and miss and last time they were all already squishy. Bought some at xmas last year and was still using in Feb.
Cheap as chips 30p cans of lidl rice pudding can be made to feel like a real treat if you heat and chuck in a bunch of saltanas, squeeze in some honey and sprinkle with demerara. £1 supermarket pate isn't all that gross, in a sandwich you can pimp up with thinly sliced pickled gherkin and maybe a slither of chutney if you are feeling fancy.
Long life milk in as a backup. If you are having it in hot drinks only, the taste difference is barely noticeable and it is still cheaper than a petrol station.
Unsmoked smallish gammon in a slow cooker on high for four hours, chuck in already boiled water and peppercorns. Eat with baked beans, coleslaw etc, or onions and pickles. Or buy frozen mash. To make pre made mash taste less pants you leave out to defrost then put in the oven with a knob of butter for 20 minutes and stir once or twice.
Waffles and suchlike can be eaten with almost anything but they are not cheap these days.
Best frozen chips we have found, been through loads, very thick cut M&S bag for around £2.50-3.00. Banging quality compared to the expensive competition. Preheat air fryer for three minutes and pop in a drizzle of rapeseed oil.
If you fancy a booze but have guilt, Lidl do £2 big bottles of cider - i don't like fizzy cider. i discovered if you open it and leave it a week to go flat, it's alright with some ice.
Pizza bases. Cheap passata. Squeeze in generous inches of tomato purée to thicken and luxuriate it up.
I am of brain power, will pop back if anything else occurs.
