To the bowl of a food processor, add the chickpeas, pistachios, almond flour, mint, parsley, shallot, and garlic, and pulse 7 to 10 times, until you reach a coarse but uniform texture. Add the remaining ingredients, then pulse, frequently scraping down the sides of the bowl, until the mixture comes together in a coarse paste.
Remove the bowl from the processor and pull out the blade. Using a 2 tsp (10 ml) capacity cookie scoop or your hands, roll the falafel mixture into balls and set onto the baking sheet. Bake for 15 to 18 minutes, or until the falafel are lightly golden and firm to the touch. Let cool for 10 minutes before serving; this will allow the falafel to firm up and reach their ideal texture.
SERVING: Serve Pistachio Falafels warm or room temperature as a bite along with hummus or a quick combination of Greek yogurt and lemon juice; in a pita with lettuce, sliced tomatoes, diced cucumber and hummus or Greek yogurt for a quick lunch; or over rice and veggies, drizzled with a sauce made of hummus thinned with orange and lemon juice for a nutritious, satisfying dinner.
STORAGE: Store Pistachio Falafels in an airtight container in the refrigerator for up to 5 days. You can also freeze the falafels on a baking sheet; once the falafels are frozen hard, transfer them to an airtight container. You can reheat the Pistachio Falafels from their frozen state by placing them on a parchment-paper-lined baking sheet in a 325°F (160°C) oven for 10 minutes.
