Cut the feta into cubes, pour the resulting fragrant oil.
Leave it in the refrigerator (it took me 3 hours).
Wash the salad, dry it, break it with your hands. In the original, it was necessary to mix 2 salads, arugula and plain, but I took only arugula. Cut tomatoes. Chop the green onions not very finely.
Vinegar (lemon juice – had to be diluted with concentrated, it turned out) whisk with mustard, black pepper. Add salt. Add finely chopped parsley and olive oil.
