If you are self-isolating, there are many local grocers and fruit and veg suppliers who are offering home deliveries of veg boxes. Do a google search for ‘veg box delivery’ and include your area/town/city in the search term and go from there.
You can also check your local council Covid-19 support pages online, as these sometimes contain lists of local businesses providing deliveries.
If you are able to go out to the supermarket, shopping for fresh veg that’s in season is a money saver, as well as hunting for deals on frozen fruit and veg that lasts longer. Some will be expensive (the organic options usually) but some won’t. Also, supermarkets often do ‘wonky veg’ sections, which are a great way to pick up fresh fruit and veg while spending less.
If you can, cooking fresh veg into stews and casseroles, then freezing, is a good way to make it last. More ideas here: https://www.nhs.uk/live-well/eat-well/5-a-day-on-a-budget/
If your budget is really stretched and you are struggling to cover bills as well as food, but can only eat fresh fruit and veg, you can be still eligible for support from your local food bank – find them online or contact your local council and discuss your food needs with them.
Everyone has things they can’t eat (or really like to eat!), and food banks work hard to make sure that people with specific needs still receive food they enjoy.
