Heat 1 teaspoon of olive oil in a sauté pan or skillet over medium high heat until hot but not smoking.
Season the branzino with salt and pepper and sear, skin-side first, over medium-high heat for 1-2 minutes. Flip to sear other side for 1-2 minutes or until light brown. Remove from pan and keep warm.
Sweat the onions until they begin turning translucent and then add the remaining ingredients, excluding the relish. Continue to cook over medium heat for 4-5 minutes. Remove from pan.
Place the sauce in a shallow bowl. Place the branzino atop the sauce and then finish with relish.
