Step 1

Prepare Green Beans - Wash the green beans thoroughly under cool water and drain well. Trim off the string ends. If the beans are very long, cut them in half. Set aside.

Step 2

Cook the Mushrooms - In a large skillet, heat the olive oil over medium heat. Add the mushrooms and ½ teaspoon salt. Saute until tender and lightly brown, 2 to 3 minutes.

Step 3

Cook the Aromatics - Add the garlic, and cook until fragrant, 30 seconds. Add the onions, and saute until translucent, 1 to 2 minutes.

Step 4

Cook Green Beans - Add the green beans, water, soy sauce, ½ teaspoon salt, and pepper to the pan. Stir to combine. Increase to medium-high heat. Cover and cook until the beans are tender and bright green, about 3 to 4 minutes. If still crisp, add ¼ cup water and steam until crisp-tender. Remove the lid and stir until the water evaporates, about 1 minute.

Step 5

Add the Butter - Turn off the heat and add the butter. Stir until melted and combined.

Step 6

To Serve - Taste and season with more salt and pepper as desired. Serve while still hot.
