bolting plants

Hi all,
I have a bunch of kailaan (Chinese broccoli) and some giant spinach that all bolted this week. I cut them back, but I'm wondering if I should just pull them out? Will they come back with noew shoots that are edible, or are they finished?

They'll probably come back. But next time they bolt, maybe you should let them go to seed. Nothing like saving your own seed for real permie fun!
