Toast the Almond Garnish : Place the sliced almonds in the small, dry skillet over medium heat. Toast for 3 to 5 minutes, shaking the pan frequently, until they are fragrant and golden brown in spots. Immediately transfer the almonds to a plate to cool completely; this prevents them from burning.
Prepare the Aromatics & Citrus : Roughly chop the scallions and garlic cloves and add them to the bowl of your food processor. Zest the entire lemon, adding about 2 teaspoons of zest to the processor. Then, juice the lemon and lime, setting aside a total of 3 tablespoons of mixed citrus juice.
Create the Herb Base : Add the cilantro, dill, parsley, and mint to the food processor with the aromatics. Secure the lid and pulse the mixture 10-12 times until everything is finely minced, scraping down the sides with a spatula once or twice.
Emulsify the Vinaigrette : Add the sea salt and optional red pepper flakes to the food processor. With the machine running on low, slowly stream in the 1⅓ cups of olive oil, followed by the 3 tablespoons of reserved citrus juice. Continue to process for about 30 seconds, or until the vinaigrette is smooth and uniformly green.
Ready the Bowl Components : If desired, gently warm the cooked farro and roasted vegetables in a large skillet over low heat for 4-6 minutes, or until just heated through.
Assemble the Harvest Bowls : Create a foundation in each of the 7 bowls by dividing the farro evenly. Arrange 1 cup of roasted vegetables over the top of each portion. Generously drizzle approximately 2 tablespoons of the zesty herb vinaigrette over each bowl.
Final Flourish : Finish each grain bowl with a sprinkle of the toasted sliced almonds for a delightful crunch. Serve immediately.
