When a guy asks a girl to cook for him, what does it mean?

I'm texting with a guy and I've got some signs that he might like me. Today I sent a picture of when I was cooking and then I described what I cooked, then he wrote "you have to cook this for me sometime". What does this mean? Did he see this as an opportunity to see if I might want to hang out with him in the future?
