Kharkiv (the east part of Ukraine) was not so friendly with the Bicycle because we didn't have any streets, or lanes for the cycle so only a few people had bicycle,s especially kids.
I moved to UA to pursue my master's degree and later I stayed there for life...
I noticed leaves of Eruca / arucola on your "hamburger". Do you like its taste and smell? Asking cuz I have the arucola growing in my garden and still not too sure about it.
!HBIT
They taste not bad at all, I hope you will also like them...
