Wipe any dirt off mushrooms with a paper towel and cut off any larger tough stems. Leave stems on any small tender mushrooms. Leave mushroom caps whole (don't slice!).
Bring a large nonstick pan to medium high heat and add enough sesame oil to lightly coat the pan (~ 1 Tbsp).
Add mushrooms and drizzle on soy sauce and lemon juice. Don't overcrowd the pan, you want the caps to be touching the surface.
Reduce heat if smoking and let mushrooms set until golden brown and starting to crisp (2-4 minutes). It's important to not move or stir the mushrooms in order to get it browned.
Flip mushrooms, and add garlic and ginger and a little more sesame oil if needed. I like to make a divet in the middle and add the garlic, ginger, and oil. See picture above in the pan.
Cook an additional 2-3 minutes or until browned.
Add salt to taste and garnish with optional chives. Happy Eating! Beckie
