That looks so delicious!!! I wouldn't be surprised if you got a lot of people stopping in at dinner time :))
The bakchoi looks a little like a leafy escarole. Like this
It's been so long since I had that. Thank you for reminding me how delicious escarole can be.
In my garden, I have many veggies similar with escarole, yes because they still in one family. So the leaf will be similar.
I hope you have a great time ❤️
