Prepare the rice according to package instructions. Preheat the oven to 425°F.
Rinse and dry the chickpeas. Transfer them to a parchment lined baking sheet and drizzle with a tablespoon of olive oil. Season with salt and a generous amount of freshly cracked black pepper. Toss to coat, and move to the oven to roast for 24-26 minutes or until slightly crisp.
While the chickpeas are cooking, get out a large bowl.
Add the mustard, lemon juice, lemon zest, garlic, honey and parsley to the bowl. Drizzle in the olive oil and stir to create a dressing. Season with salt, taste and adjust with more lemon juice, salt and olive oil as needed.
Using a peeler, peel the carrots directly into the bowl, making long strips. Toss the carrots until they are well-coated with the dressing.
When the rice and chickpeas are finished, serve them on the bottom of a bowl, and pile the carrots on top. Garnish with chopped toasted walnuts and eat immediately.
