Seared Barramundi with Olive-Herb Sauce

Combine olives, anchovy, dill, parsley, shallot and vinegar in a food processor. Pulse, scraping down the sides as necessary, until roughly chopped. With the motor running, drizzle in 3 tablespoons oil and blend until almost smooth.

Place cornstarch in a shallow dish. Pat fish dry with paper towels and season with salt and pepper. Dredge the fish in the cornstarch. Heat the remaining 2 tablespoons oil in a large nonstick skillet over medium-high heat. Add the fish and cook until golden on one side, about 3 minutes. Flip the fish and reduce heat to medium. Continue cooking until the fish flakes easily with a fork, 1 to 2 minutes more. Serve the fish with the sauce and garnished with more herbs, if desired.
