In a blender, blend the first 4 ingredients (lemon juice and 2 cloves garlic through salt and pepper) until smooth.

In a large skillet over medium heat, heat coconut oil.

To the skillet, add the chicken and cook for 5 minutes on each side, until brown.

To the chicken, add the pesto and spinach, and cook for 5 minutes, until chicken is cooked through.

In a mixer, blend the remaining ingredients until smooth. Add salt and pepper to taste and serve chicken with mashed cauliflower.
