Inspiration needed for vegetarian meals for playdates

[VenetiaLanyon]

I'm looking for things like macaroni cheese, that I can bake the night before and just stick in the oven on the day. Have to be dishes with a good protein content that will be fallen upon gratefully by visiting children. Am trying to avoid pizza if possible.

Any thoughts appreciated

Thanks GoodbyeRubyTuesday, I love the sound of your childhood jackets
