A couple of years ago, finding and planing my food intake was serious job, but luckily I don't have to anymore, because I produce my own food, and eat fresh plant and vegetables from my own garden. There is no better feeling in the world, trust me (maybe becoming a parent, I don't know yet :D ). Gardening can be extremely easy, and you would need 2 ares only to produce food for your needs. I have a property with around 2.2 acres and that's enough for our family of 4, and we he have for sale.
This is how I sustain my vegan lifestyle - by producing my own food, check it out:
