How to Make the Onion and Green Olive Relish

Making this onion and green olive relish is simple and is what makes the entire dish so beautiful.

  • Prep the lemons. Finely grate the zest from 2 of the lemons into a small bowl and set aside. Using a sharp knife slice the ends off of each of the lemons then cut the peel and white pith from the lemons; discard. Cut between the membranes to release the lemon segments into the bowl with the zest, discard the leftover membranes. Slice the remaining lemon in half and squeeze the juice into the bowl.
  • Prep the red onions. In a separate small bowl add the sliced onion and sprinkle the salt on top, let sit for 10 minutes.
  • Marinate. Add the chopped olives, capers, and 3/4 cup of olive oil to the bowl with the lemon segment, toss to combine, and cover for 30 minutes at room temperature.

How to Cook Cod Perfectly

Baking cod in the oven is simple and a great way to achieve a soft and flaky fish.

  1. Preheat the oven to 250℉. By cooking the fish at a low temperature you allow it to slowly heat to a perfectly flaky fish.
  2. Place the cod in a large shallow baking dish or oven-safe skillet and drizzle with the remaining 1/2 cup of olive oil. Turn the fish to coat and season with additional salt if desired.
  3. Bake until cooked through for 30 to 40 minutes.

Is Cod Healthy to Eat?

Though cod is a tad higher in sodium it is an excellent source of omega 3 fatty acids and is full of lean protein and vitamin B-12. This fish is also low in calories and makes an excellent healthy option for any day of the week.
