I was just paging through Bittman’s Food Matters (2008)—library copy!, which not only presents food philosophy, but also recipes. He advocates essentially eating farther down the food chain—more fruits and veggies. This also reduces your energy footprint (meat is expensive to grow).
Then, in the recipes, there’s one for roasted garlic. Take a (as in one) head of garlic and put it in the oven for 45 minutes.
There goes your green quotient down the tubes….
