What to do with greens?

[Itscurtainsforyou]

In an attempt to eat more green veg, I bought a bag of greens today. Then I realised I don't know what to do with them (bar just boiling/steaming them, which isn't very exciting).
Any ideas for fairly simple but tasty recipes?
Thanks

Mix them up in a stir fry?
I put a load of kale in with a beef stir fry last week and it accidentally went all crispy and lovely (i.e. i overdid it) but it was nice.

You can cook it on a low heat for a good while and make it crispy. Just add a little oil and salt.
Can't think of any specific recipes, sorry!

How about putting them in bubble and squeak?

I also like to stir a handful through pasta sauce in the last few minutes of cooking
