Friend who wants to come over for...?

I have a friend at school. She came over for halloween along with a few other people and we watched movies. We came up with having a movie night just me and this girl every wednesday night. this week we were both busy and last night was her only free night. i negotiated with her to go out for like taco bell or something cheap because i wanted to get out of the house. but she said she likes coming to my house because I have good food. What should I do?? Its obvious she just wants to come over for the food. Help please:D Much advice needed!!!!
