Step 1

Combine the cilantro, Fresno pepper slices, ginger, garlic, lime juice, soy sauce, sugar, and 2 tablespoons of the olive oil in a small bowl. Stir ingredients until well incorporated. Set aside while you prepare the ahi.

Step 2

Place a skillet over medium-high heat and coat with remaining 1 tablespoon of olive oil. Season ahi steaks generously with kosher salt and black pepper. Sear ahi for about 1 minute on each side to form a light crust. The cooking time will depend on how thick your ahi is cut, and whether you prefer your fish to be medium-rare or more well done. Drizzle a few tablespoons of the sauce over the ahi steaks to coat the fish (once you start searing on side #2). Transfer the ahi to a platter. Top with avocado and drizzle remaining sauce over the fish.
