Homeless

So, I have a moral dilema. There is a guy who comes to visit our house every once in a while. I think he has been here 3 or 4 times since we moved in. He is 30ish, black, and very thin. Each time he has asked if we have any money to give him because he is homeless. I don't think giving a homeless person money is what I would want to do because there is no way for me to make sure they buy food with it and not drugs or alcohol. I want to figure out how I can help this man without giving him money. Perhaps I could give him food rather than money. I want to figure out something to do for him, but I don't know where to start. Any advice?
