Once I met a woman who didn’t like to wash up after cooking, so she threw all the pots away. What a waste! She got new pots when she was robbing personal basement storage lockers. Well this salad is for her. I hope she has met somebody who likes to do the washing up.
Scrub and wash the beetroots, but keep the skin. Boil them in salted water until they are soft (can take up to an hour). In the mean while you can wash the arugola carefully and let them dry. Mix the goat cheese with the sour cream. Proportion to your own taste. I think a strong taste of the goat cheese works really well with the sweet beetroots.
Place the dried arugola leaves on a wide plate. Peel the beetroots and slice them in thin slices. Place them nicely over the arugola and dived the goat cheese mix. At last drop some whole or chopped walnuts over the salad. Serve with bread and dry white wine.
