This arugula pesto sauce is a great alternative to basil pesto! Arugula is available year-round, and gives a great flavor when used to make pesto. Not to mention, it can be used on so many things! From gnocchi, to pasta, crostini, pizza and more!
Add all ingredients (but only ¼ cup of the olive oil) to a food processor.
Process in the food processor until all ingredients are well blended.
At this point, add more oil if needed, and process again. Your arugula pesto is ready!

Notes
The amount of olive oil you add can depend on personal preference. If you like your pesto more solid, add ¼ cup olive oil. If you like your pesto more of like a saucy consistency, add the full ½ cup of olive oil
Pecorino romano adds a a tangy, sharp bite and flavor to this pesto. But if you don't have pecorino on hand, you can omit it, and just add the ¼ cup of parmigiano.
Alternative nuts to use instead of pine nuts: walnuts, almonds, pistachios or pecans will all work really well
I used an 11 cup food processor, and the ingredients fit just perfectly before processing. If you're using a smaller food processor, you may have to make the pesto in batches.
The 1 garlic clove used in this recipe gives a stronger (but not overpowering) garlic flavor to the pesto. If you like less of a garlic flavor, use a small clove or half of clove of garlic.
Add just a pinch of salt to the ingredients - the parmigiano and pecorino are already very salty, so you will not need to add much salt.
