Write about food, or even better health food and the preparation of it.
I will be writing an documenting the cost effectiveness of you cooking your own meals, as well as the health benefits.
If I manage to cover the cost of my meal with post, then it would be a tremendous success in my eyes. If I manage to convince even more people to start cooking at home way more often than eating out and also getting paid for it... now I am making a real change in the world :)
