  • 4 fish fillet (I used flounder, frozen fish can be used, de-frost and towel dry before baking)
  • 10-14 small roma tomatoes (seeded and cut into small pieces
  • 3/4 teaspoon oregano
  • 3/4 teaspoon basil
  • 1/4 teaspoon salt
  • dash hot pepper flakes if desired
  • 1/4 cup chopped fresh Italian parsley 7 grams
  • 2 1/2 tablespoons olive oil
  • 1 tablespoon olive oil for drizzling


  • Pre-heat oven to 350° (180° celsius)
  • In a medium bowl add, cut up seeded tomatoes, oregano, basil, salt, hot pepper flakes, Italian parsley and 2 1/2 tablespoons (37 grams) olive oil. Mix gently to combine.
  • Line a medium to large baking pan with a large enough piece of parchment paper (large enough to fold over the fish), line fish fillet (they can be touching) top fish with tomato mixture, drizzle with 1 tablespoon (15 grams) olive oil and fold the parchment paper to cover the fish.
  • Bake in the oven for approximately 20-25 minutes. Uncover and drain excess water, raise heat to 400° (200° celsius) and continue to bake for another 5 minutes. Remove from oven and serve immediately. Enjoy!
