Toss the herbs in a blender and pulse for 10 seconds. Scrape down the sides, add pistachio nuts and pulse for another 30 seconds. You may need to scrape down the sides a couple times.
Add remaining ingredients and pulse for a minute or until all ingredients are blended together. Again, you will need to scrape the sides a few times. It should have a bit of a chunky texture.
Shape the falafel doughs to resemble golf balls. Lay on a parchment lined baking sheet. You can squish them slightly if you want them flat, otherwise just keep them in balls. Bake for 15 minutes flipping after 10 minutes.
Serve on a pita or lettuce leaf, topped with your favourite fixings. We used yogurt mixed with dill, lemon, and garlic as our sauce and topped with red onions and cucumber.
