Pesto Penne

This is Pesto with a difference - yes, yet AGAIN.  But hey, Pesto is one of those cooking basics that can be endlessly reinterpreted, which is a good thing.  Because we've got an ongoing need to use up things creatively, not letting good stuff go to waste, right?  So, this time it is Russian kale and sorrel pesto with walnuts, walnut oil and some fresh mint.  Each time, I think, THIS IS IT, the ultimate pesto. But, probably I'll never be content to just stick with one recipe.

It made a great lunch, tossed with penne and a few of the cooked white beans from another fabulous recipe.  One I found to use the first bunch of my CSA sorrel.  I still had some left, which was the motivation here.
