Cilantro Pesto - what to do with leftover cilantro stems

Whenever I buy cilantro I always use just a bit of it and then let the rest go bad. I'm attempting not to waste anything these days, and figured out that cilantro stems can actually be used to make really good pesto, and it's a lot cheaper than basil.

You'll need cilantro, garlic, some kind of toasted nuts (I used pecans, since I had them and I hate pine nuts), lime juice, Parmesan, oil and salt. The measurements of these are relative, since it really depends on how much cilantro you have.

Pretend that the balsamic is garlic, since I never actually used any. I think I used about 6 cloves.

If you have a Cuisinart food processor, that's perfect to make pesto. Start by throwing in the cilantro, garlic and nuts. Chop them up about as much as they will go, then add the oil, salt, lime juice and Parmesan.

I froze about half of the batch, and then put the other half in the fridge. Toss with pasta, spread on bread, make chicken salad, etc. Basically anything you'd do with regular pesto you can do with this stuff.
