Pierogi - Polish jiaozi?

My Polish flatmate's food. They look very identical to Chinese jiaozi but the stuffing in side is vegetable. Maybe there is meat stuffing as well but she's not keen on?

Didn't get a chance to try as went outside for exploration - needed a pair of trainers for exercise and table tennis. But the JJB Sports at the shopping centre is closed down!

Came back and had my dinner, chicken soup with drumsticks. My Polish flatmate tried the soup only and said it was very delicious.

Next time, she can serve her Pierogi in my chicken soup :-)
