Crete has weeds growing in every stony crack; but unlike most places, Cretans devour them. Weeds of all stripe—dandelion, purslane, chicory, sorrel—are picked and braised and tossed together in a peppery mix called horta. With a citrusy squirt of lemon and a little olive oil for fat and flavor, horta is a nutritional powerhouse of iron, calcium, omega-3 fatty acids, plus an alphabet soup of vitamins. For a man on the run, it was a life saver.
