About an hour prior to the time you’d like to cook the fish, squeeze lemon over both sides of the fillet, and sprinkle a bit of salt and pepper. Refrigerate until ready to cook.
In a bowl, combine tomato relish ingredients and set aside.
Heat olive oil in a pan over medium high heat until spattering and drop in swordfish fillet. Sear about 4 minutes on one side and flip. Sear another 4 or so minutes until fully cooked. Checked for doneness by poking center with a fork. If it flakes, it’s ready.
Top with tomato-oregano relish, and serve with more fresh lemon for squeezing, if desired. Enjoy!
