Cabbage

Peak Seaon: Year-round

Perfect Pick: Tightly packed, crispy, deeply hued leaves free of blemishes. Should feel dense when lifted; it's best that the stem not have any cracks at its base.

Handle with Care: Tightly enclose cabbage in a plastic bag and store in the fridge for up to 10 days.

The Payoff: More than half your vitamin K requirement in just 1 cup.
