The meat is well boiled, and cut into lengthwise pieces. If the beef is fibrous, it can simply disassemble the fibers.
Onion cut into quarter-rings.
Cut the cucumber into strips.
Tomatoes to try to slice just like the cucumber.
Chop the greens, not granulate.
All mix, salt, add ground black pepper. I usually do not fill this salad with anything, so everyone has different tastes, even in our family it is seasoned by everyone at their discretion. Just serve separately mayonnaise, separately mix the vegetable oil with lemon juice (you can add a little mustard).
