Good Easy Recipe to Leave for Baby Sitter to Make?

My mom has to work from 4 to 9 tomorrow and our baby sitter isn't so talented in the kitchen. We have ate pizza 5 weeks in a row because we don't know what to leave the baby sitter to make. Any easy ideas that we could either leave already made so she only has to put it in the microwave or something easy she can make is what I am looking for.
