Picky friend for dinner are coming - what to cook?

He is a meat and pototoes guy and has a limited palette; she is very easygoing and open to anything. I am a vegetarian, but like to try new things. I don't have a grill. They're coming for dinner tomorrow night. I want to serve a delicious well-balanced meal. Oh, one more thing - I'm not a good cook, so this has to be easy.
