Pre-heat oven to 400ºF and line a rimmed 12" x 18" sheet pan with parchment paper.

In a large bowl add sliced onions, garlic, cauliflower florets, carrots, 2 tablespoons avocado oil and 1/2 of spice mixture. Mix to combine and spread on to rimmed baking sheet.
1 onion, 3 garlic cloves, 1/2 medium cauliflower, 4 medium carrots, 3 tablespoons avocado oil
Bake for 20 minutes.
Meanwhile place chicken breasts into the large bowl. Add remaining 1 tablespoons avocado oil, remaining curry spice mixture and lemon juice. Toss to combine and place in refrigerator to marinate while vegetables are baking.
