Pesto alternative

Here in Tampa, arugula is a winter crop, and I will soon buy a few more bottles of extra virgin olive oil plus walnuts or pecans (I'm too cheap to buy pine nuts at $16 a pound!!!) at Big Lots to make bulk batches of pesto to freeze for summer use. Yup years ago I learned about substituting arugula for part or all of the basil when making pesto and BOY is is good! Plus arugula is a much bigger "beefier" plant vs. picking hundreds of basil leaves.....try it!  John
