Some people can't prep,no money or space and now see shelves in stores emptying, prices rising.Food banks under pressure can't supply much.

My advice would be before anything else buy various stock cubes, bouillon, have chicken, vegetable and beef.

With this even if there is no other food,in a real pinch you can drink one cube in hot water.Even if you can only find a can of beans, you can make a nourishing soup which can serve more people than eating it solid.

Also try to get honey, it keeps in a jar better then sugar, tea, when things are really tight have one day only tea, the next the soup.

If you know how to make soup then when you are able to get rice,meat, freh vegetables, include these.

Start eating very frugally now and use any spare money no matter how little, to buy cans of soup, tuna, tomatoes, fruit vegetables.Keep these, even one drawer of such goods may see you through a few weeks.
