You know those humble cans of white beans you have stashed in the pantry? It’s time to dig them out and keep them on deck. They are the backbone of this wholesome greens and beans hash. Give yourself 20 minutes (maybe less!) and you’ll be tucking into creamy, blistered beans tossed in a tangle of wilted lemony greens. Top it with a runny-yolked poached egg, and prepare to feel like a real dinner superhero.
