Marinated Halibut with Cauliflower Mash and Arugula Salad

Marinate the fish in a zip lock bag or Tupperware for 1 hour (do not exceed 2 hours). Preheat the oven to 400 degrees Fahrenheit. Remove the fish from the marinade and pour the marinade into a small baking dish. Drizzle some olive oil on a hot skillet over medium heat. Sear the fish for 3-4 minutes each side until golden brown. Add the fish to the baking dish with the marinade and bake for an additional 8-12 minutes (depending on the thickness of your fish). For the cauliflower mash, steam cauliflower until soft. Add the steamed cauliflower, remaining garlic, olive oil, almond milk/broth, salt, and pepper to a food processor or immersion blender and blend until smooth. For the salad, toss all arugula, olive oil, lemon juice, Parmesan cheese (if using), salt, and pepper.
