But if people are literally 'down to their last quid' then obviously half a dozen eggs is a sensible purchase. Then sorting out a referral to a food bank.
But realistically, a box of eggs is only going to make one light meal for 2-3 people, so is only a very short term solution. Although eggs are great for making healthy low cost, quick meals that don't need much cooking so good to always have in.
What this thread is about is whether it's possible to use herbs and spices on a low budget and with food in general, there does need to be a degree of thinking ahead, because once you've bought your herbs and spices, you're much less likely to find yourself in a position where you've nothing in and no money or ideas what to make.
It's more about doing what you can to avoid finding yourself in a position when you have no food, no money, no storecupboard basics, no cooking skills, no equipment and a family used to eating convenience food so they won't eat chick pea curry. Because then, when you have little money, you could buy a tin of chick peas and a couple of potatoes and make a big curry in the slow cooker with the spices you already have.
Apart from very young adults just starting out, the people who have run out of food and have a family to feed have years of experience of feeding themselves, so it's about making the most of that time to know how to feed yourself well on a low budget, so if the shit hits the fan, you can cope without relying on unhealthy convenience food which is almost always more expensive than cooking with basic spices.
