Heat the olive oil: Heat the olive oil in a large skillet over high heat. Once the pan is hot, add the green beans. Stir often for about 4 minutes until they begin to blister and turn bright green.
1 tablespoon olive oil, 1 pound green beans
Cook the mushrooms: Add the sliced mushrooms and cook for another 3 minutes. They should soften and release some moisture while the green beans stay slightly crisp.

Add the aromatics: Reduce the heat slightly. Stir in the garlic and ginger, cooking for about 30 seconds until fragrant. Don't let the garlic brown or it can become bitter.
1 tablespoon fresh garlic, 1 teaspoon ginger
Make the sauce: Add the soy sauce, vegan oyster sauce, maple syrup, and sesame oil. Toss well until the vegetables are evenly coated.

Reduce the sauce: Let everything cook for 1 to 2 minutes until the sauce becomes glossy and lightly coats the vegetables.
Season: Taste and season with salt and black pepper if needed.

Serve: Garnish with sesame seeds and chili flakes. Serve immediately while the green beans are still crisp-tender.
