Heat oil in a large non stick skillet over medium high heat.
Pat the halibut fillets dry with paper towels. Season both sides of each fillet generously with salt and pepper.
Place the flour in shallow dish. Dredge the halibut lightly in flour mixture and place in hot pan.
Sear the halibut until golden, about 3 minutes. Turn and cook until other side is golden, being careful not to overcook. Remove the halibut to serving plate and allow to rest.
Deglaze the pan with white wine. Melt the butter in the wine and then add the garlic, capers, and parsley. Simmer 2 minutes. Turn off the heat. Add the lemon juice to pan and stir to combine.
Divide the pasta between shallow pasta bowls. Top each portion of pasta with halibut portions. Pour the pan sauce evenly over each plate, spooning the capers, garlic and parsley onto the fillets. Serve immediately.
