1. Prepare the Basic Barbecue Sauce. Place an oven rack in the middle of the oven and preheat the oven to 400°F. Lightly oil a rimmed baking sheet.
2. Cut the salmon into 4 portions; season the salmon with salt and pepper to taste. Coat the pieces on all sides with the Basic Barbecue Sauce and place them on the baking sheet. Bake for 10 to 12 minutes for medium, or to the desired doneness. Meanwhile, prepare the Dill Pickle Cucumber Slices.
3. To serve, transfer the salmon to serving plates and spoon the cucumber slices over them, about 1/3 cup on each.
