1. Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Season the cod on both sides with salt and pepper, and add to the pan, skin side down. Sear the fish on both sides, about 5 minutes per side, until it flakes easily. The flesh should be opaque, but still very moist, when cooked.
2. In the meantime, warm the olives on the stove in a small amount of olive oil. Top the cod with the Cherry Tomato, Basil, and Garlic Confit and a scattering of warm olives and serve on a bed of Potato Puree.
