Moo's Marinated Mushroom Salad

1 1/4 lbs small mushrooms
1 small onion, finely chopped
1/2 cup parsley, chopped

Marinade
6 T olive oil
2 T lemon juice
1 clove garlic, crushed
1/2 tsp. whole black pepper, crushed
1/2 tsp. whole coriander seed
1/2 tsp. whole mustard seed
1/2 tsp. salt

Wash mushrooms and remove stems. Add mushrooms to a sauce pan of boiling salted water (enough water to cover mushrooms). Simmer uncovered for 5 minutes. Drain and let mushrooms cool. Set aside. Mix together olive oil, lemon juice, garlic, pepper, coriander seed, mustard seed, and salt. Add mushrooms, onion and parsley. Blend thoroughly. Cover and chill, stirring occasionally. Set aside for at least 2 hours (best overnight). Serve in the marinade.
