  • 1.25 pounds cod fish filets
  • 2 tablespoon avocado oil, divided
  • 3 cloves garlic, minced
  • 2 oz lime juice (about 2 limes)
  • 10 ounces crushed tomatoes
  • 1 tablespoon sweetener of choice
  • 1 teaspoon smoked paprika
  • 1 teaspoon oregano
  • ½ teaspoon red pepper flakes, optional to taste
  • 1 tablespoon Habanero hot sauce, optional to taste, use any hot sauce you like
  • ½ cup chopped cilantro
  • 20 whole cherry tomatoes, halved
  • 1 whole bell pepper, diced
  • ½ whole red onion


  • Preheat your oven to 375°F. Season your cod with salt and pepper, set aside. Season your vegetables with some salt and pepper then set aside in a bowl.  
  • Warm your cast iron skillet over medium heat. Add 1 tablespoon of avocado oil to your skillet. Add your garlic and dry seasonings. Cook until fragrant, about 30 seconds to one minute. Pour in crushed tomatoes, and the juice of half a lime. Next, add in your sweetener and your hot sauce. Adjust seasonings to your preference, then take the sauce off the heat.
  • To your vegetables, add the remaining avocado oil, the juice of half a lime and then about ⅓ of the cooked tomato sauce.
  • Add the vegetables to the skillet, then put the cod fish on top and slather it with the remaining tomato sauce. Bake in the oven for about 15-20 minutes, until cod is cooked thru.
