First, caramelize the onion in a neutral oil on medium heat. When they start to brown, add the garlic, beans, hot sesame oil, and soy sauce. I use 4ish tablespoons, but add according to your palate. Cover the pan, leaving a small crack for steam to escape. When the beans start to pop and/or get mushy, add the herbs and spices. Add the spinach and a little more soy sauce. Stir well and enjoy. You can serve this over rice or pasta, or eat it plain. I like to melt a little gouda on top.
