Mystery Vegatable

Since last week, women have been selling a mysterious green leafy vegetable on the street corners. The vegetable looks like tulip leaves. Finally I decided to bite the bullet and ask what it was. Unfortunately - I can't remember the name in Russian except that is starts with "ch"\

Still, I followed her directions for the salad and it was pretty tasty - the leaves are bit spicy - almost like green onion.

Directions: 1 bunch of the "Ch" leaves. 3 Boiled Eggs, some mayonnaise. Chop, Dice, Mix, and serve. I also added a little salt and the lady said that parsley and onions could be added - but the leaves are spicy enough without adding onion.

Any guesses as to what this vegi is?
