Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Toss 4 cups cauliflower florets and 6 peeled garlic cloves with 2 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper. Spread on a baking sheet and roast for 25 minutes until tender and lightly browned.
  2. Step 2: While cauliflower roasts, season 2 boneless skinless chicken breasts on both sides with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1 tsp chopped fresh rosemary.
  3. Step 3: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add chicken breasts and cook for 5-6 minutes on each side until golden brown and internal temperature reaches 165°F. Remove from heat and let rest.
  4. Step 4: Transfer roasted cauliflower and garlic to a food processor. Add 1/4 cup unsweetened almond milk and pulse until smooth and creamy, scraping down sides as needed. Adjust seasoning with remaining salt and pepper.
  5. Step 5: Plate chicken breasts alongside 1 cup cauliflower mash per serving and garnish with extra rosemary if desired.
