Preheat oven to 250 degrees F.
Season trout fillets and prawns with salt, garlic, and lemon pepper. Heat 2 tablespoons olive oil in a large saute pan over medium-high heat and then place trout fillets, skin-side down. Saute fish for 1 minute, turn, and cook for 1 more minute, or until fish is just cooked through. Add 1/2 cup chardonnay to the pan and hold in a warm oven until ready to serve. In another saute pan, heat remaining 2 tablespoons olive oil, add shrimp, and cook for 1 to 2 minutes on each side. Add the remaining 1/2 cup chardonnay to the pan and hold in warm oven.
In the middle of each entree plate, place 1/3 cup hot mashed potatoes. Place 2 spears of asparagus on top of the potatoes. Place 1 portion of cooked trout on top of the asparagus, and then place 1/3 cup additional mashed potatoes on trout. Place 1 tablespoon of cooked spinach on the potatoes and top with 2 prawns. Drizzle each plate with a little Lemon-Shallot Beurre Blanc Sauce, and garnish each plate with 3 gaufrette chips.
Place potatoes in a medium saucepan and cover the potatoes with water by 1-inch. Add 1 teaspoon salt and bring to a boil. Reduce the heat, and simmer until the potatoes are
fork tender, about 12 to 15 minutes. Drain into a colander. In a mixing bowl, mash potatoes until no lumps remain, and then add butter. Next add cream, remaining 1 teaspoon salt, and pepper. Cover and keep warm until ready to serve.
In a small heavy saucepan, boil the Champagne vinegar and chardonnay with the shallots over high heat until only 1 tablespoon of liquid remains. Add heavy cream and cook for 1 minute. Remove from heat and add butter, 1 tablespoon at a time, whisking after each addition until melted before adding more. When all the butter has been incorporated, whisk in the lemon juice, kosher salt, and white pepper. Hold the sauce in a warm spot but not over direct heat.
Heat oil in a deep fryer to 350 degrees F. Alternatively, fill a large, deep, heavy pot halfway with oil and heat to 350 degrees F. Using a mandoline, make very thin, cross-cut potato slices. Fry until golden brown. Remove to a paper towel-lined plate to drain and salt lightly.
