Write a short letter to your friend about how you can help hungry people: prepare a meal,a cake,do shopping or have a magic "stone soup"

Dear ,
I am writing to you to talk about how can we help hungry people.
I personally like helping homeless people, who are hungry. So you can help them too! You can prepare a meal for them, or you can buy some food in the shop. Also if you want you can buy them a cake - they'll be happy! Furthermore, you can go shopping and buy a packet of food for them. 
Well, I think that's all! Write me a letter what you think about this idea.
Love,
