Cilantro Walnut Jalapeno Pesto - omg so good! Used a whole jalapeno with seeds, tossed with some spaghetti. Great amount of heat. At first a little too cilantro flavored but fine the next day. Maybe try a blend of cilantro and basil or arugula next time.
Opted for yummy kale after failing to find basil at 5 separate grocery stores but I think I may like kale pesto better than basil anyway. It also looked nothing like the picture above. mine was a very bright green.
