Marinated Mushrooms - cooking recipe

Ingredients

1 whole lemon plus 1/4 c. fresh lemon juice
6 c. water
1 tsp. chopped fresh oregano
2 lbs. fresh medium mushrooms, ends trimmed
2 tbsp. white wine vinegar
1/2 c. extra-virgin olive oil
1 tsp. salt
3/4 tsp. fresh ground black pepper
2 Tbsp. minced parsley
1 medium onion, minced

Preparation

Cut lemon in half; remove seeds. Cut into very thin slices. In a large saucepan, bring water, lemon slices, and oregano to a boil. Add whole mushrooms, place a heatproof plate on top to keep mushrooms from floating to the top, and cook for 5-6 minutes, until mushrooms turn white. Drain.
