I’ve invited 2 lovely colleagues for lunch- one is vegetarian and has a 5 year old and a 4month old baby. The other has a 4 year old and a 2 year old. I want to look after them and give them a lovely lunch and also some time to relax if they can. I want to be able to spend as much time helping with the children as possible, and not be stuck in the kitchen sorting food out. What would you offer a mixed bunch like this that they would all eat and that I could mostly sort beforehand?
