Combine all the ingredients in a medium bowl. Taste and adjust seasonings and oil to your preference. Set aside. (I like to make this at least 1 hour ahead so all the juices and flavors meld together).
Swordfish:
Preheat oven to 400°F.
Rinse and pat dry your fish. Season your fish on both sides with the seasonings listed above.
Heat the olive oil on medium high, in an oven safe and non stick pan. When it's hot add the fish to the pan. Let them sear, do not disturb for at least 3-4 minutes.
Flip them over and immediately transfer the pan to your preheated oven. Roast in the oven for 5-6 minutes. Internal temperature of fish should read between 130°F and 135°F. Do not over cook.
Remove the fish from the pan and place on a platter to rest for 5 minutes.
Top with your 'salsa' and enjoy.
Notes
Optional: To serve, garnish with some lemon slices and parsley.
