Combine parsley, thyme, sesame seeds, lemon zest, and fennel fronds. Season scallops with salt and pepper. Roll the sides of the scallops in herb mix. Coat a cast iron skillet or a nonstick pan with olive oil, about 2 tablespoons. Place scallops in hot skillet and sear about 2 minutes per side until the scallops are opaque and firm.
Orange and Fennel Salad:
Place the orange supremes and fennel into a bowl. Zest and juice the lemon over the orange and fennel. Season, to taste, with salt and pepper and drizzle with olive oil. Toss gently and place onto serving plates.
