Heat oil in a large, non-stick skillet over medium-high heat. Pat fish dry and season with salt and pepper. Place in skillet, skin-side down. Cook for 4 minutes, and then flip and continue cooking until fish is fully cooked and flakes easily with a fork.

Meanwhile, combine chives, parsley, lemon zest and juice, garlic, salt and pepper flakes in the bowl of a food processor. Turn processor on and stream in oil. Mix until well combined, scraping down the sides of the bowl with a spatula if necessary.

To serve, drizzle 1 tablespoon of sauce over each fillet. Enjoy!
