In a small bowl, combine the Miso paste, Soy sauce, Garlic powder, Mirin, sesame oil, and Water. Mix until smooth and set aside.
1 tablespoon miso paste , 1 tablespoon regular soy sauce, ½ tablespoon mirin , 1 teaspoon sesame oil , 1 teaspoon water, Pinch garlic powder
Heat avocado oil in a large skillet over medium-high heat. Add the green beans, leaving them to sear a little and cook, tossing occasionally, until they begin to blister and develop lightly seared spots.
1 tablespoon avocado oil , 1 pound fresh green beans
Add the pat of butter to the skillet. Toss the green beans until the butter melts and coats them evenly.
1 tablespoon butter or plant-based butter
Lower the heat and then pour the prepared miso sauce into the skillet. Toss the green beans very well until evenly coated and cooked through. Do not burn or high-simmer the sauce, or else it will burn.
Transfer to a serving platter and serve immediately with lemon wedges on the side. Enjoy miso green beans!
