What to cook?πŸ˜ͺ

My best friend's family is coming tomorrow night for dinner (our best friend is living with us) and his family is like our family because his mother has always been there for my husband.
I really have no idea what to cook πŸ˜©πŸ˜‚πŸ˜‚πŸ˜‚
I'm a pretty good cook might brag about that a little but I have no idea because I actually do wanna cook something special for em so if you've got any suggestions then just feel free to comment (please) πŸ˜‚πŸ’“
We're gonna be about 15 people and 4 of us are pregnant
Sorry if this is the wrong group didnt know where to post this but you're all mommys so I thought you might have some ideas.
