Prepare the Grains: Place the pearled farro in a fine-mesh sieve and rinse under cold running water until the water runs clear. Shake off any excess water and set aside.
Build the Aromatic Base: In a large Dutch oven or heavy-bottomed pot, heat the extra virgin olive oil over medium heat. Add the chopped leek and cook, stirring occasionally, for 5-6 minutes until softened and translucent. Add the minced garlic and whole wheat orzo, and continue to cook for 1-2 minutes more, stirring constantly until the orzo is lightly toasted and fragrant.
Toast the Farro: Add the rinsed farro and the zest of both lemons to the pot. Stir for 1 minute to coat the grains in the aromatic oil.
Simmer and Infuse: Pour in the low-sodium vegetable broth and fresh lemon juice. Increase the heat to high and bring the liquid to a boil. Once boiling, immediately reduce the heat to the lowest setting. Cover the pot with a tight-fitting lid and let it simmer gently for 25 minutes.
Rest and Steam: Turn off the heat. Quickly stir in the rinsed chickpeas, then promptly replace the lid. Let the pilaf stand undisturbed for 10 minutes. This critical resting period allows the grains to absorb the final amount of steam and firm up perfectly.
Finish and Serve: Remove the lid and fluff the pilaf with a fork. Gently fold in the freshly chopped parsley, mint, dill, and the black pepper. Serve warm.
