Eat greens every day! This is one of Dr. Joel Furman's top tips in his book Eat to Live. Eating greens floods your body with important macronutrients and cancer-fighting antioxidants. I feel so energized when I eat a lot of greens, and kale is one of my faves.
I like to steam this entire bag and drizzle on some maple balsamic vinegar, eat it raw and massaged as a big salad, or add bunches to soups.
