Preheat your oven to 450F or 425F convection. Line two baking sheets with parchment paper. On one baking sheet, add fennel, carrots, 2 tablespoons olive oil, and ½ teaspoon salt and toss to coat. On the other baking sheet, add the chicken, remaining 1 tablespoon oil, and ½ teaspoon salt. Bake the chicken for 10-15 minutes and the veggies for 20-25 minutes, or until carrots are tender and chicken is cooked through.
Scatter the kale over the veggie sheet pan (recommend massaging the kale with a drizzle of oil to soften it before adding). Place the chicken on top (you can keep it whole or slice it up).
Add all dressing ingredients to a medium bowl and whisk to combine. It should be thick, but drizzle-able. If too thick, add a splash of water to thin it out (this will depend on how thick your tahini is).
Drizzle ⅔ of the dressing all over the sheet pan. Top with toasted nuts or seeds. Keep extra dressing on the table to drizzle over plated salad! This salad is delicious on it’s own or with a slice of crusty buttered toast.
