I would re-sow it if you still have seed any time from now until August. Especially if the weather is cooler it should do better. I don't know the variety you mention (perhaps the 'surprise' is the prickles! But if you stir fry it or steam it for a minute or so, the prickles won't be a problem. Lots of Chinese greens are like this and it shouldn't be a problem, though as you say you might not like to eat it raw. For sandwiches, a fantastic Chinese greens is mizuna. This produces masses of cut and come again leaves, is so easy to grow, and with a bit of cover will crop well into early winter. You can stir fry it or eat it raw like lettuce, but it's far tastier than lettuce.

Sarah,

Some Chinese greens do have slightly hairy leaves but they don't 'sting'. (Though might feel slightly prickly) Have you got a photo of them as this would help identify what you have got?
In any case this would be very early for Chinese cabbage to be harvested as normally you sow it now for autumn use, otherwise it goes up to seed prematurely without heading.
Do you know what the name of your variety of greens is? Pak Choi, for example, or just a generic Chinese leaf?
