There is no easier way to get more greens into your life than with a bag of prewashed (or frozen!) spinach, so I use a lot of spinach in my recipes, both here on the blog and in my books, Eat More Plants and Good For Your Gut. Spinach is high in vitamin A carotenoids as well as folate. Spinach is a high oxalate vegetable, which can decrease absorption of minerals like iron, but enjoying it cooked will help you get more from its naturally high content of calcium and iron.
I love wilting a handful of spinach into a vegan tofu scramble, layering it on my vegan breakfast sandwich or blending it up in a pina colada smoothie! Spinach fan already? Try my sweet potato spinach salad or my incredibly fast and delicious vegan spinach dip.
