Steam potatoes until almost cooked through (about ten minutes).
In a wide sauté pan or braiser, heat 3 TBS Olio Taibi Nocellara Extra Virgin Olive Oil over medium high heat.
Add the onions and red pepper flake and sauté until soft and golden.
Add the can of tomatoes, including the the juice. Crush tomatoes gently apart with the back of a spoon (you can also crush by hand before adding to pan).
Add capers and olives.
Simmer gently for about 5 minutes.
Add cod to sauce, cover pan, and cook over medium low heat for 10 minutes, occasionally stirring gently. (The cod will begin to break apart, that's ok)
Add potatoes and continue to cook, with pan covered for about 20 minutes, or until potatoes are tender.
Gently stir in parsley.
Serve warm with a drizzle of Olio Taibi Nocellara Extra Virgin Olive Oil on each dish.
