Since the advent of the microwavable meal, frozen peas have been a staple in the American diet (at least for those of us who still eat our vegetables). Alas, it turns out that the frozen pea has far fewer antioxidants and nutrients than any other kind of pea as a result of being blanched before going in the freezer. The season for fresh peas is short, but you don't need to look for fresh anyway, because dried peas are your gold standard, carrying more antioxidants than even farmers' market fare. Our favorite way of eating them? Just toss them into a big pot of split pea soup.
