To make the soup, warm the olive oil in a medium saucepan over medium heat. Add the shallot and sauté until tender, about 7 minutes. Add the lemon zest and juice, wine and broth and bring to a simmer, cover, and keep warm over low heat.
To make the puree, combine the peas, parsley, garlic, salt and pepper in a food processor and puree. With the machine running, add the extra virgin olive in a steady drizzle. Transfer the pea puree to a small bowl and stir in the Parmesan. Set aside.
Meanwhile, place the fish on a parchment lined roasting dish. Sprinkle with salt and pepper and bake to 10 to 12 minutes, depending of the thickness of the fillets.
Stir the lemon soup and divide among 4 bowls. Place a large spoonful of pea puree in the center of each bowl. Place the Sea Bass atop the mound of puree and serve right the way. Drizzle a bit more soup over the fish.
