What does it mean when a guy friend invites himself to my house for dinner?

This guy that i work with said that he wants to come over to my house for dinner. He said that he’s hungry and needs some homemade food. He basically invites himself to my house. He also said that i got a nice house. Why would a guy act like this? What do you think about his behavior?
