Gaining

Hi, i'm weightgaing but i don't have much money for extra food so, can you tell me very fatty foods that don't kill me and they are cheap?
I had another idea but for me is not a good idea. I tought to ask money on sites like this but i don't want to post pics and people can exchange me for a fake account. Tell me what you think and some foods. Thanks

not too much but in this month i'm having some money problems because i moved and now i live alone
