I spend about $500-$600 per month for a family of 4 in the Bay Area. And it's very healthy - fresh veggies and fruit are cheap at Asian groceries stores if you buy in season. Buy in bulk, cook large portions so you have multiple meals with less work. For $20 you can cook enough food for 8 individual meals. And that $500-$600 per month is not really trying to squeeze every dollar. We could knock off another $100-150 if we absolutely had to by replacing some of the more expensive items with cheaper, but still healthy options.
