  • For gremolata
  • 1/2 cup fresh parsley chopped
  • 1 clove garlic minced
  • 2 lemons washed and dried
  • olive oil
  • 1/4 cup capers
  • For toast
  • 1 small head cauliflower cut into small florets
  • 1/2 cup water
  • 1/2 cup gruyere cheese shredded
  • 1 large egg beaten
  • 1/2 teaspoon salt
  • 1/2 teaspoon garlic powder
  • pepper to taste
  • Wild Sardines


  • For the gremolata Zest the skin of both lemons. Add lemon zest and garlic to parsley and toss. Cover and set aside.
  • For the cauliflower toast Preheat oven to 450°F Line a baking sheet with parchment paper and brush with olive oil.
  • Pulse a few florets of cauliflower at a time in your food processor until the cauliflower pieces are the size of couscous, about 3 cups.
    Next bring ½ cup of water to a boil in a small saucepan. Add the cauliflower to the pan. Stir. Turn the heat off and cover the pan. Let the pan sit covered for 10 minutes.
    Then remove the lid.Transfer to a cheesecloth and twist cheesecloth into a pouch. Squeeze out as much of the moisture as possible, almost 1 cup of liquid. It is important for the cauliflower rice to be dry.
    Then place in a large mixing bowl and add egg, cheese, garlic powder, salt and pepper. Mix well. Divide in eight sections and shape into toast-like squares. Bake for 25 minutes, until golden.
  • Place 2 sardines on each slice of toast. Top with gremolata, drizzle with olive oil and garnish with capers.


There's a soft bone that you may want to remove from each sardine. (I don't mind the bone; it is a good source of calcium and so soft that you can't choke on it.) However, if you prefer removing the bone it is very simple to do.
Sardines are a very delicate fish so very gently take the tip of your knife and slit open each sardine and remove the long thin bone. Then fold the two halves together again. Do this for each sardine.
