Preserving Nasturtium Leaves?

[wifezilla]

Anyone put these up for the winter? Blanch & freeze? Stir fry and bag?

I know you can pickle the seed pods, but I hate to have all those leaves go to waste.

I enjoy eating the flowers- but don't know anything about the leaves...Just use them as greens?? I blanch and freeze swiss chard leaves- can't see why it wouldn't work for any green...

That's kind of what I was thinking. I also HAD a bunch of sweet potato leaves, but the hail shredded them. I will wait for the plants to recover before harvesting any leaves.
