Preheat oven to 400°F.

Line up the fennel slices on a rimmed baking pan. Place the beets in a line next to the fennel and the red onion in a line next to the beets. Drizzle with olive oil, salt, and pepper and lightly toss each vegetable to coat.

Roast the vegetables at 400°F for 30–35 minutes. Remove from oven and allow to cool.

Meanwhile, heat the olive oil in a medium saucepan over medium-high heat. Add the Israeli couscous and stir to coat, letting it toast slightly. Add the water and salt and bring to a boil.

Cover and reduce heat to low. Simmer until all the water has been absorbed, approximately 10 minutes. Remove from heat and allow to cool.

Combine the vinaigrette ingredients and whisk or pulse to emulsify.

To assemble the salad, layer the Israeli couscous, fennel, beets, onion, and pomegranate arils.

Drizzle with the vinaigrette.

Garnish with extra parsley and mint and serve warm or at room temperature.
