The nav bar has some issues - people tend to like the home button to be on the left-hand side of the nav bar (not the right) and some elements are unclear - it is non-obvious that the buttons drop down, or what they do or where they take you.
Add some kind of newsfeed or notification which can come up showing the latest news. Involving the charity. This would likely involve a title, body of text & an image, to appear on the home page. Could also list off previous posts (use the same component from the food page?)
Of course, a backend would also need to be created to add, delete and edit the posts into the database.
Add an additional button to mark the cupboard is empty.
This could be done in two ways - simply drop an email to Phil saying the cupboard is empty, or open a new page with the ability to specify what is missing - e.g., biscuits, squash, fruit, etc. - and then send an email to Phil specifying exactly what is missing.
