I got a back of rape leave (canola plant leaves) in my CSA this week. What should I do with them?
I haven't been able to find much information about cooking with them online. Have you ever cooked them? Any ideas on how to use them? I also got some of the little buds.Thanks for your help!

There are lots of Italian recipes, particularly from Puglia. Here is my favorite way to prepare rapini: saute onions, pepperocini, and garlic in olive oil along with diced bacon or some other tasty pork, add the rapini, which has been washed and chopped, then let cook until the rapini is tender. If you don't want to use pork, anchovies are a good substitute. This stands alone as a vegetable, or you can serve over farro, polenta, or pasta. Open a good Negroamaro, Primitivo or Nero d'Avola to accompany.
I know certain kinds of rape have been used by humans for a long time now, but which kinds, and used how? There isn't much documentation pre 1800s. The kinds used in the 19th through 20th Century are ones that do well in a monoculture setting and these are the ones that are thought to have caused harm. But they are probably different than the ones used historically. My feeling is that there isn't enough reliable data available, but that eating small quantities probably won't cause harm. Also it could be that rape refers to a larger category of crops in Europe than it does in North America.

Personally I would advise against eating Rape leaves, or any part of the Rape plant. Rape was a very popular crop back in the age of Steam because the oil worked as a wonderful lubricant in the engines. Then when the car came along and steam went out of fashion there was a need to find new uses for rape... so they started feeding it to animals. Sources from that time showed that it caused a lot of fast growing cancer in animals and feeding it to livestock was banned in several places.
However, much of Canada is great for growing rapeseed. So some smart people got together and created a kind of rape that was low in the acid that was thought to cause cancer in livestock. This rape descendant is called CANOLA - CANadian Oil Low Acid (or some acronym like that).
CANOLA being one of the larger and of huge financial important crops in Canada has a lot of power behind it and a lot of power in the press to paint it in a positive light. Because of this, the research into the health of CANOLA on animals and humans is controversial. There is a lot of evidence saying it's good for people and that it's bad for people, and the results of each study correlates to who is funding the study. I would love to see some truly independent research, but I haven't found it yet.
In my personal opinion (and I stress this is my personal opinion) I'm not a huge fan of CANOLA. I'll eat it, but if there is an alternative, I'll spend an extra dollar and eat non-CANOLA instead. Why I feel this way is that science is beginning to show (what conventional wisdom knew) that it's not one factor (like a single acid in a plant) that causes cancer or other health issues. Quite often it's ratios between things, or maybe the method of processing, or maybe it's something else in the plant that combines with other things in the diet (theoretical example, rape plus corn were often combined in livestock diets). Getting rid of one specific acid may not have solved the problem that caused cancer, maybe it was just the factor that increased the speed of it developing. As is the case with many of the newer foods in our diet, we only have a few generations of experience as to how it interacts with our bodies.
But like I said, this last bit is my opinion and there is a lack of consistency in the research to say yah or neigh to my concerns. Hopefully this served to alert you to the controversy and get you reading and deciding for yourselves if you like eating CANOLA or not.
If I were to eat these, I would probably blanch them then add them to stir fry or pasta dish. Or maybe blanch them, then fry them in butter with garlic...mmm garlic.
Develop your own culinary profile and learn first hand what works with what. Sorry if that isn't much help
