Calorie for calorie, leafy green vegetables like spinach with its delicate texture and jade green color provide more nutrients than any other food– vitamins K, A, C, B2, B6, E and magnanese, folate, magnesium, iron, calcium, potassium, tryptophan, and dietary fiber. Buy it fresh or frozen. Since it’s Spring Break, daughters Marla and Janice are home. This morning I scrambled the whites of eggs, spinach, chopped tomato, reduced fat feta, and served it with a wedge of lemon and rye toast. If you squeeze lemon on food, it tastes like butter!
