The 200 grams shimeji mushrooms have a puck of growing medium attached to the base, so you want to cut this off with a knife. This should make the mushrooms fall apart.
The 250 grams shiitake mushrooms can have some growing medium and other debris on the caps, so use a paper towel to wipe them clean.
Then, trim off the tips of the stems and cut the caps into quarters or eighths, depending on the size.
Shred 100 grams maitake by hand into bite-sized pieces.
Add 3 tablespoons olive oil and 20 grams garlic to a pan and fry over medium heat until the garlic is soft and fragrant.
Add the mushrooms and saute until they start to soften.
Add ¼ teaspoon salt and ¼ teaspoon black pepper and continue sauteing until the mushrooms are browned and not releasing liquid.
Add 1 tablespoon soy sauce, 1 tablespoon balsamic vinegar, and 2 teaspoons honey and stir until the mushrooms are glazed, and there is no liquid left in the pan.
