Sorrel , Chicory, Endive and more. Bitter greens are packed with vitamins A, C and K, and minerals like calcium, potassium and magnesium. They are shown to promote great skin, a strong nervous system, healthy blood clotting and contain phytonutrients shown to support eye health.
My favorite recipe for bitter greens is Potato, Leek and Ricotta Pizza with Sorrel Puree.
I swap the sorrel for a mix of bitter green and the leeks for onions.
