Preparing Salsa Verde fast and fresh
Even for 12 servings, the total quantity of herbs is small; so, in my opinion, the best way to chop it is with knife. 

Maybe you need to improve your technique. 

Use a big sharp knife, on a big cutting surface. 

Get all the herbs aligned and press them together with your left hand (or your right hand if you are lefty like me) in a tight pile over the surface. 

Lean the side of the knife on your fingers, placing the tips of the fingers away from the cut. 

Practice and you'll see that it's fast and easy and the results are the best.
