How to Make It
Preheat oven to 500°F. Place a rimmed baking sheet in oven (leave pan in oven while it preheats).
Combine sweet potato, 2 tablespoons oil, rind, 3/8 teaspoon salt, pepper, Brussels sprouts, 2 tablespoons Parmesan cheese, shallots, and cauliflower in a bowl. Spread potato mixture on preheated pan; bake at 500°F for 15 minutes or until golden brown.
Combine remaining 2 tablespoons oil, remaining 1/4 teaspoon salt, tarragon, and vinegar in a large bowl. Add arugula; toss to coat. Divide arugula mixture among 4 plates. Top evenly with vegetable mixture, remaining 2 tablespoons Parmesan cheese, and almonds.
