Preheat oven to 400 degrees F
Combine all vinaigrette ingredients except olive oil in a small jar with a lid. Cover with lid and shake to combine. Add olive oil, cover again, and shake to combine. Set aside.
Heat a pot of water for the couscous (follow the package instructions - my couscous called for 1 3/4 c water to 1 1/4 c couscous). While the water is heating, chop your veggies. Cook your Israeli couscous according to the package instructions.
Toss sliced carrots and diced turnips on a rimmed baking sheet, drizzle with 1-2 Tbs olive oil, toss to combine, sprinkle with salt and pepper and roast in 400 degree oven for 10 minutes. Remove from oven, flip veggies with a spatula, and roast 5 more minutes.
Toss cleaned, chopped brussels sprouts in 1 Tbs of olive oil. Remove veggies from the oven, add brussels sprouts to the pan, roast for 5 more minutes. Chop the kale while you're waiting. Add kale to the pan, sprinkle with salt and pepper if desired, and roast the veggies one final time for 5-10 minutes, until kale is slightly crispy.
Combine veggies and cooked Israeli couscous in a large bowl, toss to combine. Serve with vinaigrette on the side so each person can add the amount they like. Garnish with almonds or pistachios if you wish!
