Preheat the oven to 425°F with a rack in the middle position and line the bottom of a 9x13 baking dish with the lemon slices, creating a bed for the fish.
Combine the panko breadcrumbs, olive oil, and chives in a small bowl.
Place the fish filets directly on top of the lemon slices, and season with salt and pepper. Top each filet with ¼ cup Not Just Pesto followed by the panko mixture, equally dispersing on each filet to create a crust
Place in the oven for 15-20 minutes (depending on the thickness of your fish) until it flakes easily with a fork. Garnish with a drizzle of olive oil and some extra chives. Serve immediately alongside salad or roasted veggies
