Drizzle a small amount of oil on bottom of blender
Add arugula, Parmesan, pine nuts, half of lemon juice, salt and pepper
Start blending and slowly add oil
Blend till you get a good consistency
Taste and add more salt, pepper and rest of the lemon juice if needed.
Notes
I love garlic that's why I added so much. But if that is too much use one clove. For cilantro parsley pesto you just need to switch out a few ingredients 1 cup packed cilantro leaves 1 cup packed parsley 2 tablespoons almonds(some say blanched almonds but I don't think it's necessary) And continue as normal.
