Almost every morning, I bake, scramble, fry or flip eggs for breakfast. So, when I also remember to mix in some antioxidant-rich dark leafy greens like kale or spinach, I want to pat myself on the back. How virtuous! How clever! How easy, with a bag of washed greens stashed in the crisper drawer. It takes only a couple of minutes more to prep an egg casserole and pop it into the oven than it takes to poach or fry a couple of eggs, and the casserole will feed a crowd, or provide a week's worth of breakfasts (or lunches, or light suppers). I can't explain how a little bit of bacon, usually so salty, makes this egg and cheese casserole so sweet, except that it draws sweetness out of the slightly bitter kale. If bacon isn't your thing, or for a similar vegetarian option, try a kale, mushroom and caramelized onion breakfast casserole instead.
