Well known for its tasty unopened flower heads, the entire broccoli plant deserves praise and a place in the kitchen. The florets and stalk can be roasted in a very hot oven to bring out an often-unknown sweetness, or steamed, sautéed, and enjoyed raw. But, broccoli should always be served bright green and al dente, never overcooked. The leaves make an excellent cooking green, prepared in the same way as collards. Nutrients: dietary fiber, vitamins C and K, potassium, folate, beta-carotene and the phytochemical quercitin.
