Green beans with mushrooms and onions

Serves: 4
Serving size: 1/2 cup
Prep time: 10 minutes
Cooking time: 10 minutes

Ingredients:
8 oz green beans, trimmed
2 tsp olive oil
4 oz sliced mushrooms, such as button, cremini, portobello, or shiitake (stems discarded)

1/2 cup thinly sliced onion
1 medium garlic clove, minced
1/8 tsp salt
2 tsp fresh lemon juice
Pinch of pepper

Cooking method:

1. Fill a medium saucepan three-fourths full with water. Bring to a boil, covered, over high heat. Cook the green beans, uncovered, for 5 minutes, or until tender-crisp. Drain well in a colander.
2. Meanwhile, in a medium nonstick skillet, heat the oil over medium-high heat, swirling to coat the bottom. Cook the mushrooms, onion, garlic, and salt for 5 minutes, or until the mushrooms are soft and lightly browned, stirring frequently. Stir in the lemon juice, pepper, and cooked green beans.
