A friend just told me. They in the dining room at work decided to take care of those who observe the fast: in the menu appeared the positions "borsch meat" and "borsch lean". At the delivery, a friend asked for a plate of borst. The cook gently puts vegetables in the plate with the bouillon, and asks:
Do you have meat?
and yes.
From this same pot, the cook catches pieces of meat and adds it to the plate.
