There was one food I was able to consume freely and that was soup. I forgot how nice soup is, even for a vegetarian like me. It is easy to swallow and smells nice and it is quite cheap. Also if you have a dried up baguette, you can eat it with the soup and it would become soft again. There is dehydrated soup that you just add hot water, and there is ready prepared soup in cans and plastic tubs. Perhaps I will eat a lot more soup for now on.
If you buy a multi pack of soup you get change from 50p for each unit and the dehydrated cup soups come with 4 sachets and they are less than £1, good for taking at work. Plus. There are many different recipes to choose from, even if you are vegan.
