1. Wash mushrooms gently. Trim stalks and cut in thin slices up and down, through stalk and cap. Put them in a medium to large non-metallic bowl.
2. Squeeze a lemon over them. Stir in minced garlic. Grind lots of pepper on them. Mix. Pour olive oil over all.
3. Let sit 2-3 hours, stirring occasionally if you’re home.
4. Just before serving, add a little more olive oil if mushrooms are dry. Add salt to taste (up to 1 tsp). Add chopped herbs and mix again.
