I do the cooking at home. Where we eat no more than 100 grams of meat a day and have 'tons' of fresh vegetables. I prepare the vegetables with a wide range of herbs, spices and such. We also keep on hand lots of fruit, yogurt and great breads.
Post-apocalyptic novels tell you that in the future there is some great war. I would tell you that most cops say that it's going on right now.
