How to Make It
Preheat the oven to 450°. In a small bowl, whisk the olive oil, grapefruit juice and coriander.
On a baking sheet, toss the carrots with 3 tablespoons of the dressing. Spread the carrots in a single layer and roast for about 20 minutes, turning once, until golden and tender. Season with salt and pepper.
Meanwhile, in a small bowl, mix the almonds, grapefruit zest and parsley. Transfer the carrots to a platter along with the avocados. Drizzle with the remaining dressing, top with the grapefruit gremolata and serve.
