Are cooked nettles safe for dogs to eat?

I know a lot about herbs, but unfortunately don't know everything about what is safe or not safe for dogs, as some really healthy foods for humans can be bad news for dogs.
I eat a lot of nettle tops, steamed like spinach, or in soups and stews. They are abundant at the moment where I live, are very nutritious, and free food!

The other day I steamed a few tops, (no salt) chopped them and added them to my dog's dinner. I often give her some carrot, or cabbage or other greens with her dinner -just a small amount, and she enjoys a few veggies with her meat and kibble. She loved the nettles, ate them happily.....didn't do her any harm at all, but I do wonder if I should give them to her again or not.

I don't know if anyone will know the answer to this. I ran a search on it online but couldn't find anything.
Anyone have any knowledge of this?

That's stinging nettles (urtica dioica) (cooked not raw)
