Place all of the ingredints as well as 1/4 cup olive oil into the food processor.
Turn the machine on and let it run for 1 minute.
Scrape down the sides. Add the additoinal 1/2 cup of olive oil if the pesto is still really thick and dry. I almost alwasys add in the extra amount.
Turn the machine on and let it run for another minute.
Spoon the pesto into an air-tighet conatiner and store in the fridge or freezer.

They can scrape down the sides of the machine as well as help clean up. Make sure to still supervise them around the sharp food processor blade. Have them follow along with the pictures down below for step-by-step instructions.Advanced: you can have them get all of the ingredients out, measure everything, process the pesto before putting the ingredients back where the come from and cleaning up.
