Runner Beans with Caramelized Onions & Dijon Sauce

I’m always looking to cook beans in a hearty application that doesn’t involve meat. After all, beans are a protein on their own. From lentils to split peas to baked beans with ginger, chipotle and hoisin, this has offered varied and delicious results. Why am I doing this? I have no idea, I’m not even a vegetarian. I just want to see how best it can be done.
