Peel the onion, finely chop and pour hot water to remove bitterness. Allow to stand 10 minutes, drain the water and carefully squeeze the onion. You can use pickled onions. To make the dressing. Mix oil, salt, pepper, lemon balm and garlic powder.

Cheese cut into small cubes. Mushrooms, if you take fresh, cleaned and wipe with a damp cloth and cut into small slices. (I used canned.)

Lettuce to break it into small pieces.

All the ingredients are thoroughly mixed.
