I have not prepared a salad, here today decided to prepare. I have subtleties in the preparation of this dish. Firstly like a lot of beets. Potatoes do not put (since I do not eat), and replace it with canned white beans in its own juice. Everything else as usual. If the beets are very sweet, then sprinkled with lemon juice. When there, add the capers. Also cut a small bunch of onions, and cilantro. And of course Perche. The vinaigrette turns out beautiful and delicious
